Many people ask how to get the best translation quality from machine translation (MT) without acknowledging the fact that machine translation quality cannot improve without human input. Machine translation will only yield you the best language translation that a computer alone can generate. This means that if you’re hoping for a machine translation application to autonomously generate high-quality translations of idiomatic phrases, local jargon and dialectical variations, you’re going to sabotage your translation projects. So, how to get the best translation quality from machine translation? Well, first we need to reinforce why you can’t get high-quality translation from machine translation software alone.

This is part 1 of a 5 part series, going through each of the principles in SOLID, how they have aged, and investigating if we can achieve a deeper more comprehensive understanding of what each principle is trying to achieve. To Uncle Bob's own words, SRP is commonly misunderstood to mean A module should do one thing and one thing only. In reality, SRP is meant as a corollary to Conway's law, which in simple terms state that software will naturally be segregated to mirror the topology of the teams building the software. Microservices is probably the most extreme example of this law. If you have one team dealing with user notifications and another dealing with user analytics you can bet that these two features will end up being split into separate services. This is because the communication …  ( 5 min )

As someone who's been building with AI tools over the past few years from training small language models to integrating APIs into automated pipelines, I’ve seen firsthand how fast the ecosystem is evolving. What once felt like the edge of innovation (like chatbots and image classifiers) now feels like table stakes. Today, we’re moving beyond task-based intelligence into something far more powerful Agentic AI. If you’re a developer or engineer working with AI, the shift from traditional ML models to goal-driven autonomous agents isn’t just theoretical. It’s redefining how we build products, write code, and deploy intelligent systems. This article breaks down what Agentic AI really is, how it compares to traditional approaches, and why you the builder need to understand the mechanics b…  ( 5 min )

In the fast-evolving world of software delivery, two terms have risen to prominence: DevOps and Platform Engineering. While both aim to accelerate software development and improve reliability, they approach the problem from different angles. In this post, we’ll unpack the key differences, explore how they complement each other, and help you decide where to focus your efforts depending on your team’s needs. What is DevOps? Key principles of DevOps include: Continuous Integration & Delivery (CI/CD) Infrastructure as Code (IaC) Automation of manual processes Monitoring and observability DevOps isn't a team or a tool it's a philosophy. But in practice, organizations often assign dedicated DevOps engineers to implement pipelines, automate infrastructure, and act as a bridge between developers a…  ( 4 min )

The landscape of IT operations is undergoing a profound transformation, driven by the convergence of Infrastructure as Code (IaC), Artificial Intelligence (AI), and intelligent automation. This evolution is pushing IaC beyond its traditional boundaries, ushering in an era where infrastructure management is not just automated but also predictive, self-healing, and highly intelligent. The manual effort and potential for errors in writing IaC configurations have long been pain points for development and operations teams. AI is poised to revolutionize this by assisting in or even autonomously generating IaC configurations. Imagine an AI assistant that, based on high-level requirements or existing application code, can suggest or create the necessary Terraform, Ansible, or Kubernetes manifests.…  ( 6 min )

I'm not "All In on AI" at all. I'm still quite skeptical about the current LLM-based AI assistant hype. Of course, I'm still using AI, despite its pros and cons and its supposed enormous waste of energy, privacy issues, bias, and hallucination. But we definitely "need to talk about "Vibe Coding"", as Giorgi Kobaidze nails it in his DEV post (I'm All In on AI, But We Need to Talk About Vibe Coding), stating important hacker culture aspects like "journey is more important than destination", and why we don't want to go back to the not so good old times when StackOverflow was the go-to place to copy and paste.

This guide walks you through a robust procedure to auto-decrypt a LUKS-on-LVM setup at boot with a USB key. It assumes you already have your system set up with LUKS encryption on LVM. The core idea is simple: keep a dedicated USB stick at home to unlock your system effortlessly, and leave it behind whenever you head out, so your machine stays securely encrypted on the go. I extensively tested the procedure in multiple VMs and on real-world installs of Ubuntu 24.04 and Pop!_OS 22.04. Until reaching that point, I repeatedly broke my VM while trying outdated guides, AI-generated suggestions, and other unreliable sources—until I found my own way and then passed it to real setups.

Recently, I systematically tested the coding abilities of various models on a platform like ChatGOT that combines multiple AIs. Here are my test results: Claude 4 Sonnet is clearly leading in agent capabilities. When given clear requirements, it can write documentation, create tests, and write code. It can also debug, search for documentation, and correct code, continuously working for hours until all tests pass. In this aspect, Claude is unbeatable; GPT and the entire Gemini lineup cannot compete. When it comes to data structures and algorithms—essentially “hard intelligence”—the O3 series excels the most. Only O3 consistently provides optimal algorithms and architectural solutions. Claude often comes up with suboptimal algorithms. However, while it has fewer high-level errors, it tends to have a lot of low-level mistakes. Gemini’s hard intelligence is slightly weaker than O3 but considerably stronger than Claude 4. In terms of following instructions, Gemini is slightly better than GPT, and while it may be the most powerful overall, it is rarely utilized to its full potential. Most of the time, I use O3 as a professional architect and algorithm engineer to tackle the most challenging parts, while Claude acts as a junior programmer, gradually filling in various details and steadily working in the background. Gemini’s strong instruction comprehension and extensive knowledge, albeit with some hallucinations, are mostly useful in conversational modes.  ( 3 min )

What should an Operating System provide in terms of design?

If you’re a Perl developer, you’ve probably heard it before: “Is Perl still a thing?” Let’s explore where the opportunities are today and how to find them. Despite not being the trendiest language, Perl continues to power core infrastructure in fields like: Finance – for transaction processing and batch scripting Bioinformatics – thanks to CPAN’s rich ecosystem System Administration – especially in legacy-rich environments Telecom & Hosting – for custom automation and reporting The reality is, companies with decades of code running in Perl aren’t eager to rip and replace something that still works flawlessly. One major shift in recent years is the rise of remote-first hiring. More companies are hiring global developers to work on existing Perl systems—whether it's maintaining codebases, modernizing legacy apps, or integrating Perl into cloud workflows. These roles aren’t always posted on major job boards. That’s why using niche platforms is key. General job boards often bury Perl listings under unrelated content or make it difficult to filter accurately. That’s why developers increasingly rely on specialized platforms like Perl-Jobs.com — a focused job board built specifically for the Perl community, offering remote, freelance, and full-time listings from companies that actually want your Perl skills. It saves time and connects you with opportunities that are actually relevant. Perl isn’t dead—it’s just not loud. There are still solid, high-paying roles out there for developers who know how to write clean, efficient Perl code. And with the right tools and platforms, you don’t have to hunt blindly to find them. So whether you're actively job hunting or just keeping an eye on the market, it’s a good time to dust off the resume and see where Perl can take you.  ( 4 min )

** What is Event-Driven Architecture? 🤔** Event-Driven Architecture (EDA) is a design pattern where application components communicate through the production and consumption of events. Instead of direct service-to-service calls, systems react to events that represent something meaningful that happened in the business domain.

Previously, I never really understood the phrase “runs on potatoes” back in 2016, until I had the scope to work with a Unity game development team and play a game that is developed with the Unity engine and works on a 1GB RAM Android phone. If you have mostly developed and tested on your dev machine or a flagship device, trust me, you are missing out on a very real part of the market that lives and breathes budget phones. 🔄 Stop Instantiating Everything If your game has bullets, enemies, or anything that comes and goes frequently—and you’re still using Instantiate() and Destroy() every time—you’re going to run into performance hiccups. What we did: Built a really basic object pooler. ## 🎨 Sprites + UI: Less Is Definitely More I once saw a junior dev make a mobile game with 4096x4096 textures. It looked stunning. It also ran at 9 FPS on our test phones. What worked for us: Keeping sprite atlases small and compressed (512x512 or 1024x1024 max). ## 💡 The Lighting Trap Baked lighting is your friend. Real-time lights? Not so much—especially with shadows. ⚠️ Garbage Collection: Silent Performance Killer The profiler became our go-to tool once we realized GC spikes were causing microstutters. The biggest culprits? ## 🧪 You Need to Test on Actual Crap Phones Seriously, when your only test device is an emulator or a Pixel 8, you are not serious about tackling issues that your game may encounter post-launch. ## 📌 Final Thought As a game developer, you should remember one thing that when developing a game, you need to make it run well for everyone, especially those not using a flagship phone, which is the real challenge. It is not about hacking your way to 60FPS. It is about understanding your audience and optimizing your game quality accordingly. When you are building games for low-end devices and want more tips and guidance to succeed in this industry, I would genuinely love to hear from you.  ( 4 min )

During these last days I'm participating in discussions on a redesign of a landing page for an existing product. It may be perceived by many as an easy task, but it's not. The challenge lies in creating a landing page that not only looks good but also effectively communicates the value proposition of the product. It's very easy to be dragged into aesthetics, but they are not enough. The landing page must be easy to navigate and to read. It must use a language that is easy to understand and that speaks directly to the target audience. Additionally, the content must be clear, concise, and compelling. It must answer the question "What's in it for me?" and provide a clear call-to-action.

Hey folks! Today, let's talk about some crucial user authentication operations in HarmonyOS app development, especially functions like signing out, deleting accounts, and re-authentication that can sometimes be confusing. Grab your snacks and drinks, let's dive in! An Elegant Way to Sign Out Users When a user wants to switch accounts or leave your app, you can't just close it abruptly. Try this super useful signOut() method: import { auth } from '@kit/accountIdKit'; // Call this when the sign-out button is tapped It automatically clears the token and user information after sign-out. The Serious Business of Account Deletion ⚠️ This operation is like "deleting your account and running away," so make sure to have a confirmation step in your UI! Here's the core code: auth.deleteUser() User taps the "Delete Account" button. Re-authentication for Critical Moments When a user performs a sensitive action (like changing a payment password), the system might suddenly require them to sign in again. This is where you use reauthenticate: // Example with password verification Phone verification code Practical Pitfall Guide Don't panic when you run into issues. Try these common solutions: Q1: Why can I still get user info after calling signOut()? Check if there are multiple caches that haven't been cleared. Inform users in advance that their cloud data will be deleted. Check the network connection status. Provide clear error messages (don't just say "Operation failed"). A Heart-to-Heart Honestly, the most challenging part of the authentication module isn't the code, but handling all the edge cases. I recommend that you: Wrap sensitive operations in try-catch blocks.

Indexing the pages of a website is the number one step to ranking on its search result pages. So when you get a notification that some pages failed the crawl test, it puts you in a state of disarray and confusion. This solves the problem: Confirm domain ownership (easy peasy) either through G-tags or your GA4 account. Check the domain endpoint. Google rarely indexes endpoints that are critical. An example of a critical end point - sureway.com/dashboard. These type of pages must be excluded from being crawled by search engines using the Disallow rule in your robots.txt file. Ensure unindexed pages are internally linked to the primary domain. Irrelevant content. Only include relevant pages for index. Run technical audits on affected pages to fix broken links or other negatives like page speed. Should be <5s. Bonus Points: Sometimes all you have to do is literally do nothing and simply wait. Antithetical yes but does it work yes.  ( 3 min )

For many years, improving CPU performance meant increasing clock speed → allowing more cycles per second. But today, we’ve reached practical limits in how fast we can push frequency due to power, heat, and physical constraints. As a result, modern CPU design focuses less on running faster and more on doing more per cycle. To achieve this, processors use three key architectural techniques: Superscalar execution SIMD (Single Instruction, Multiple Data) Multicore parallelism Together, these allow a CPU to complete multiple operations in a single clock cycle → making better use of each tick without increasing the clock rate itself. Before diving into these techniques, it’s important to understand CPU pipelining, the foundation of all modern CPU execution, which is covered in a separate article…  ( 5 min )

In Rust, "release profiles" are predefined and customizable sets of settings with different options that allow programmers to control compilation options flexibly. Each profile is independent. Cargo mainly has two profiles: the dev profile used when running cargo build, and the release profile used when running cargo build --release. The dev profile is the default suitable for development, while the release profile is suitable for building optimized release binaries. You may see these names in the build output: $ cargo build Compiling cargo1 v0.1.0 (/rust/cargo1) Finished dev [unoptimized + debuginfo] target(s) in 0.67s $ cargo build --release Compiling cargo1 v0.1.0 (/rust/cargo1) Finished release [optimized] target(s) in 0.11s The output shows dev and release, indicating t…  ( 6 min )

OAuth 2.0’s authorization code flow relies on a client secret to prove the client’s identity when exchanging an authorization code for tokens. But what happens when your “client” is a mobile app, a single-page app, or a CLI tool? (environments where you can’t safely store secrets) That’s where PKCE (Proof Key for Code Exchange) comes in. Originally added to OAuth 2.0 for mobile, PKCE is now mandatory in OAuth 2.1 for all public clients. It thwarts interception and replay attacks by binding each authorization code to a one-time secret. Public clients can’t hide secrets: Mobile apps and SPAs run on user-controlled devices or browsers: any embedded secret is extractable. Code interception is real: Without PKCE, an attacker on the same network or with a malicious browser extension could grab y…  ( 4 min )

Hello everyone. Today, let’s summarize the data types in Cangjie. let arrayList1 = Array([1, 2, 3, 4, 5, 6]) //截取 arrayList1.slice(0, 1) //倒序 arrayList1.reverse() //查询 arrayList1.indexOf(1) Next comes the ArrayList type, which adds operations such as adding, inserting and deleting on the basis of Array: let arrayList2 = ArrayList([1, 2, 3, 4, 5, 6]) //在头部添加 arrayList2.prepend(0) //在尾部添加 arrayList2.append(7) //在指定位置添加 arrayList2.insert(2, 0) //删除元素 arrayList2.remove(1) Finally, there is the ObservedArrayList type, and correspondingly, there is also the ObservedArray type. They are typically used for state management. When the content of the array changes, they trigger the UI to update. let map = HashMap([('姓名','幽蓝'),('职业','码农')]) //修改 map['姓名'] = '123' //删除 map.remove('职业') //取值 map.get('姓名') //清空 map.clear() That’s all for today’s content.

🧠 What is Feature Engineering in Data Science? Feature engineering is the process of transforming raw data into meaningful input for machine learning models. It involves selecting, modifying, or creating new features (columns or variables) from existing data to improve model performance. Think of it as teaching your model how to think better. Without good features, even the best algorithms will underperform. Even if you're using advanced models like XGBoost, Random Forest, or Deep Neural Networks, the quality of your input data (features) often has a bigger impact than the model itself. “Better data beats fancier algorithms.” — Peter Norvig (Google Research Director) Handling Missing Data Imputation: Fill missing values with mean, median, mode, or predictive models.

Imagine two artists locked in a fierce competition. One, the generator, is a talented forger, striving to create incredibly realistic counterfeit masterpieces. The other, the discriminator, is a seasoned art expert, tasked with identifying the fakes. This constant battle of creation and critique is the essence of a Generative Adversarial Network (GAN). GANs are not about creating physical art, but rather, they are powerful machine learning models capable of generating remarkably realistic data – images, text, music, even code – that mimics real-world examples. At their core, GANs consist of two neural networks: the generator and the discriminator. They work in tandem, constantly improving each other through a process of adversarial training.

📚 Aula de Matemática – Razão e Proporção 📏 1. Razão 🔎 O que é Razão? Razão é uma comparação entre dois valores, feita por meio de uma divisão. A razão entre os números a e b (com b ≠ 0) é dada por: Razão = a ÷ b = a : b A razão entre 10 e 2 é: 10 ÷ 2 = 5 → 10:2 = 5 Se em uma sala há 8 meninas e 12 meninos: Razão meninas:meninos = 8:12 = 2:3 (dividindo por 4) Proporção é a igualdade entre duas razões. Se: a/b = c/d dizemos que a, b, c e d estão em proporção. Se: a/b = c/d Então: a × d = b × c O produto dos extremos é igual ao produto dos meios. Verifique se 2, 3, 4 e 6 estão em proporção: 2/3 = 4/6 → 2 × 6 = 3 × 4 → 12 = 12 ✅ Proporção entre salários: João recebe R$ 2.000, Maria R$ 3.000 e Carlos R$ 5.000 A razão entre os salários é: 2000 : 3000 : 5000 = 2 : 3 : 5 Usamos proporções para resolver regra de três, onde comparamos duas grandezas. Exemplo: Se 4 lápis custam R$ 6, quanto custam 10 lápis? 4 --- 6 10 --- x → 4x = 6 × 10 → x = 60 ÷ 4 → x = 15 Resposta: R$ 15,00 Sempre simplifique as razões. Na proporção a/b = c/d, use a propriedade dos meios e extremos para resolver. Se a razão envolve unidades diferentes, transforme-as antes de calcular. (IFCE – adaptado) A razão entre dois números é 5:3. Se a soma deles é 64, quais são os números? Resolução: Chame os números de 5x e 3x (mantendo a proporção). 5x + 3x = 64 8x = 64 → x = 8 → Números: 5×8 = 40 e 3×8 = 24 ✅ Resposta: 40 e 24  ( 4 min )

Setting Up NVM on macOS (One-Time Setup) If you're a developer working with Node.js, managing multiple versions of Node across different projects can get messy. That's where NVM (Node Version Manager) comes in a handy tool that lets you easily install, switch, and manage multiple versions of Node.js. In this guide, we’ll walk you through a one-time setup of NVM on your macOS system. By default, macOS uses the Zsh shell, so we’ll work with that. Open the Terminal app. You can find it via Spotlight (Cmd + Space, then type Terminal). Make sure you're in your user’s home directory: List all files (including hidden ones) to check if .zshrc already exists: ls -a touch .zshrc This file is where you'll store shell configurations, including NVM-related settings. Use the official installation script from the NVM GitHub repository: https://github.com/nvm-sh/nvm curl -o- https://raw.githubusercontent.com/nvm-sh/nvm/v0.40.3/install.sh | bash Once installed, you need to reload your shell configuration so NVM is available in the terminal: source ~/.zshrc To confirm everything went smoothly, run: nvm --version  ( 3 min )

Let’s be honest—API integration is one of the most deceptively complex tasks in modern development. From the outside? Looks simple. Plug one system into another, pass some data, hit an endpoint. Done, right? In practice? Welcome to the wild world of mismatched schemas, brittle auth flows, unpredictable rate limits, and half-baked docs. That’s why it absolutely blows my mind when I see low-code platforms treating integration like a drag-and-drop form builder. Yes, visual tools are great—but pretending that non-developers can handle enterprise-grade integration without a hitch? That’s how teams end up rewriting everything six months later. 👨‍💻 Integration Is a Developer’s Job Here’s the truth: if your API integration handles anything important—like syncing customer data, processing invoi…  ( 4 min )

After 24+ years of working with software delivery teams, through countless sprints, PRDs, vibe code sessions, and retro postmortems, one thing is abundantly clear: what slows us down isn’t the complexity of the product, it’s the SHEER REPETITION of how we build it. Where AI Currently Helps (and Fails) 1. PRDs to AI Prompt Convert PRDs into Code What’s repetitive: You already wrote the logic in the spec. Now you're just repeating it in a form GPT understands, without any context of the rest of the project. 2. Vibe Coding / Iterative Prompting Vibe Coding Fundamentals In 33 minutes What’s repetitive: Each change means another prompt. Want to add error handling? New prompt. Align with team’s standards? Another prompt. It's copy–paste, regenerate, repeat. 3. Manual Stitching and Fixing What’s repetitive: You debug structure misalignment, resolve missing references, rewire file paths—stuff that AI should’ve known if it had context. So… What’s the Real Problem? The Better Way: Automate the Setup You don’t write PRD-based prompts. You don’t vibe the same prompt five different ways. You don’t fix what AI didn’t know. Instead, your personal AI knows the spec, the screen context, the naming conventions and auto-builds the first working draft. All you need to do is the important stretch: enhance architecture, refactor for performance, and apply dev intuition where it actually matters. That’s the work that matters to developers. And that’s exactly what we built. Enter HuTouch: The Dev Repetition Killer Converts PRDs, UI designs, and code context to prototypes in one go Automatically integrates API using postman or 3rd party APIs Retains your coding standards for other tasks in the project Automates unit test creation, code review process Unleash your true potential and let HuTouch do the rest.

Hi, Developers! 📊💥 Today, we tackle an advanced binary search problem — LeetCode 2040: Kth Smallest Product of Two Sorted Arrays. It combines elements of search space reduction, pairwise products, and the nuances of positive, negative, and zero multiplicands. Let’s unpack this elegantly and see how we can find the kth smallest product efficiently! You're given two sorted integer arrays nums1 and nums2, and an integer k. You must return the kth smallest product of the form nums1[i] * nums2[j], where: 0 <= i < nums1.length 0 <= j < nums2.length The arrays may contain negative values and zero A brute-force approach of generating and sorting all products would take O(N*M) time and space, which is too slow for arrays of size up to 5 * 10^4. Instead, we apply binary search on the product value…  ( 6 min )

Here are 10 simple but powerful JavaScript tips, each with an example you can copy-paste and play with right away. map() vs forEach() — Know When to Use const numbers = [1, 2, 3, 4]; const mapped = numbers.map(num => num * 2); // returns new array const forEachResult = []; numbers.forEach(num => forEachResult.push(num * 2)); console.log(mapped); // [2, 4, 6, 8] console.log(forEachResult); // [2, 4, 6, 8] 🧠 Tip: Use map() when you want to return a new array. Use forEach() when you just want to run side effects (like logging or pushing). const user = { name: 'John', address: { city: 'Dhaka' } }; console.log(use…  ( 5 min )

Quantum Machine Learning (QML) stands at the forefront of a computational revolution, bridging the gap between the nascent power of quantum mechanics and the established might of classical artificial intelligence. Far from being a purely theoretical concept, QML is rapidly transitioning into a realm of practical exploration, with tangible applications emerging and maturing for real-world impact in 2024-2025. The current landscape of QML is largely defined by its "hybrid" nature, where classical computers handle data preprocessing and model optimization, while quantum processors accelerate the most computationally intensive parts of an algorithm, such as complex calculations or high-dimensional data analysis. This synergistic approach allows researchers and industries to harness the unique …  ( 7 min )

Chaos Engineering is a critical practice for building resilient and reliable software systems, especially in today's complex, distributed environments. It's not about creating chaos for the sake of it, but rather a disciplined approach to proactively identify weaknesses before they cause outages. By intentionally introducing controlled failures, we learn how our systems behave under stress, allowing us to fix vulnerabilities and improve overall system stability. Think of it as a vaccine for your infrastructure – a small, controlled dose of failure to build immunity against larger, uncontrolled disasters. For Site Reliability Engineers (SREs) and DevOps teams, embracing Chaos Engineering is no longer optional; it's a fundamental pillar of modern operational excellence. It helps shift from a…  ( 7 min )

Every software product, from the simplest to the most complex AI-driven platform, starts with an idea. Maybe it struck you during a conversation, while reading a book, or in the middle of a frustrating work process that screamed for a better solution. But having an idea is not the hard part. Turning the idea into a functional and valuable product is where the challenge begins. In product development, two powerful approaches help innovators bring their vision to life. These approaches are Proof of Concept and the Minimum Viable Product. While both of these serve the larger goal of validating a product idea, they do so in different ways and at different stages of the development journey. Confusing between the two or choosing the wrong one can lead to wasted time, lost money, and missed opp…  ( 9 min )

Understanding Basics Syntax for Beginners Have you ever tried to talk to someone who speaks a different language? It can be frustrating because you don't understand the rules they're using to communicate! Programming is similar. Computers don't understand English (or any human language) directly. They need instructions written in a specific syntax – a set of rules that tell the computer exactly what to do. Understanding basic syntax is the very first step to becoming a programmer, and it's something you'll be asked about in almost any programming interview. This post will break down the fundamentals in a way that's easy to grasp. Think of syntax like the grammar rules of a language. Just like English has rules about how to form sentences (subject-verb-object), programming languages have …  ( 6 min )

At Tigris, globally replicated object storage is our thing. But why should you want your objects "globally replicated"? Today I'm gonna peel back the curtain and show you how Tigris keeps your objects exactly where you need them, when you need them, by default. Global replication matters because computers are ephemeral and there's a tradeoff between performance and reliability. But does there have to be? Storage devices can and will degrade over time. Your CPUs aren't immune from it either, recent Intel desktop CPUs have been known to start degrading and returning spontaneous errors in code that should work. Your datacenters could be hit by a meteor or a pipe could burst: being in the cloud doesn't mean perfect reliability. But failovers and multiple writes take precious time. We write yo…  ( 8 min )

That was kind of a misleading title, but I wanted to get your attention. The truth is that DynamoDB Streams have a maximum retention period of 24 hours and there is no way to extend that. When you do need more than 24 hours the default solution is to use Kinesis Data Streams, which can retain data for up to 365 days. While it would be easy to just move to Kinesis, this comes with extra cost which may not be justified for all use cases. At the time of writing this I actually am using Kinesis Data Streams for a project, but the only reason we are using it is because we need to retain data for more than 24 hours in case of a failure in the processing lambda. At the time this was built time was of the essence, and we needed a solution that would work out of the box. Kinesis Data Streams is a f…  ( 6 min )

Lifeforce at 40: Cannon’s Glorious Train-Wreck Cannon Films, masters of low-budget sleaze turned surprise high-rollers, poured serious cash into Tobe Hooper’s space-horror epic Lifeforce. With a Bond/Jedi cinematographer, Henry Mancini’s lush score and VFX crews fresh from Star Wars and horror classics, it looks way more expensive than anything else in their catalogue—yet still oozes that cheeky Cannon exploitation vibe. The plot’s a deliciously bonkers mash-up: astronauts nab three seemingly dead humanoids (two guys and one very naked Mathilda May) from an alien ship masked by a comet, only for them to unleash life-draining “space vampires” on Earth. Peter Firth’s level-headed hero (and a briefly possessed Patrick Stewart) combat absurd logic twists, unapologetic nudity and hilarious one-liners. It’s equal parts stylish eye-candy, sleazy cult fun and so-bad-it’s-good “shitsome” brilliance.  ( 3 min )

TL;DR: Disney+ UK quietly pulled James Cameron’s 1989 sci-fi classic The Abyss after spotting that a long-banned scene—where a real rat is dunked into a vat of fluorocarbon liquid—had snuck onto the April streaming upload. The British Board of Film Classification had outlawed the bit under 1937’s Cinematograph Films (Animals) Act and the 1984 Video Recordings Act, yet a loophole let it slip past because streaming services aren’t held to the same cut-it-or-lose-it rules as cinemas, DVDs or broadcast TV. Why it matters: The RSPCA slammed the “streaming loophole” that lets animal-cruelty footage play unchecked in our homes and called for consistent protections across all platforms. In response, Disney has yanked the movie until it can reinstate a version with that notorious rat scene removed—just like every other UK release.  ( 3 min )

TL;DR: Actor Derek Dixon—who’s appeared in 85 episodes of Tyler Perry’s BET drama The Oval—has filed a $260 million lawsuit in Los Angeles Superior Court, accusing Perry of using his industry clout to promise career opportunities in exchange for tolerating escalating sexual harassment, assault and professional retaliation. Dixon alleges Perry sent explicit texts (“What’s it going to take for you to have guiltless sex?”), threatened to kill off his character if he didn’t comply, and on multiple occasions forcibly groped him. Perry’s attorney calls the claims “completely fabricated” and vows to fight what they describe as a “shakedown.” The suit, first reported by TMZ, lays out screenshots of the alleged messages and details Dixon’s attempts to set boundaries while keeping his role—and hopes for a pilot deal—alive.  ( 3 min )

TL;DR At a Washington State Summer Con fan event, Cobra Kai’s on-screen villain Martin Kove allegedly grabbed and bit co-star Alicia Hannah-Kim on the arm—drawing blood and leaving bruises—when she tapped him on the shoulder to say hello. A shaken Hannah-Kim filed a police report, and though she chose not to press charges, the incident was documented, and Kove was escorted out of the convention. Kove later told officers he was “just messing around” because they “play fight” on set, but he admitted it was wrong and apologized. The eye-opening altercation underscores how far off-screen antics can get when real boundaries are crossed—even among longtime castmates.  ( 3 min )

Here’s the quick lowdown: The Cobra Kai team (Josh Heald, Jon Hurwitz & Hayden Schlossberg) tried early on to get Hilary Swank—who played Julie Pierce in 1994’s The Next Karate Kid—to pop up in season 6 with just a cameo, but she respectfully passed. Despite having a neat, low-commitment idea, the timing wasn’t right for her. Swank’s busy welcoming twins and juggling new projects, so the creators didn’t push it. They say they’re still holding out hope for her return down the road—“fruit on the vine” for future Miyagi-verse adventures—even though no official spinoffs are in the works.  ( 3 min )

What Happens When Machines Lift the Weight for Us? Let’s kill the myth now: the version of “learning” that built saints out of suffering and heroes out of memory work is dead. The sacred pilgrimage through confusion and hardship—where friction itself was virtue—has been quietly, unceremoniously automated out of existence. Of course, the best teachers always knew that learning was more than pain or repetition; it was transformation. But for generations, the grind—whether memorizing Latin declensions or cramming for calculus—was the price of admission to knowledge. No more. Today, the burden is carried not by our minds, but by the machines we’ve built. The funeral was silent. The eulogy written by an algorithm. For centuries, we mythologized human learning as a rite of passage—a hazing rit…  ( 6 min )

Every App Deserves a Solid Foundation Modern web development moves fast. When building a web application from scratch, developers often begin with a clear idea — a business model, some planned features, and a database schema. Frameworks like Symfony, Laravel, or CakePHP provide a solid starting point, and it all seems simple at first. But then reality strikes. Beyond the business logic and core functionality, there are countless infrastructure requirements every app eventually needs: User authentication and password recovery Role-based access control and permissions Administration dashboards Navigation menus Configurable settings Widgets, plugins, and theming support Media handling and file management Localization, logging… the list goes on. These are not unique selling points. Th…  ( 6 min )

UserJot just hit 5,000 users, and I've been thinking about the tools that got me here. Not because they're special or revolutionary – they're not. But because they've become such a natural part of how I work that I barely think about them anymore. These aren't productivity hacks or optimization tricks. They're just the tools I open every morning and actually enjoy using. The combination has created this nice feedback loop where I can ship features quickly and stay connected to what users actually want. Here's what my daily stack looks like. I've been using Cursor for a few months now, and it's changed how I write code. Not in some dramatic way – more like having a really helpful coding buddy who's always available.

Introduction: What is Permission Delegation? The proposed Permission Delegation feature represents a significant upgrade in operational flexibility and security for token issuers, notably by enabling clear segregation of duties. It empowers issuers to delegate specific account actions or transaction types to other designated accounts without the need to share the primary issuer account’s keys. This allows specialized accounts to be authorized for their defined roles instead of being added to the issuer’s main Multi-Signature configuration where any rules are uniformly applied across all transactions regardless of business function. Permission Delegation provides issuers with far more granular control over their operations, facilitating the segregation of duties required to manage divers…  ( 9 min )

Ever looked at your code and wondered what really happens when you hit "run"? I mean, deep down, past the libraries and frameworks, how does your if statement actually... if?

So, Why Build a Whole Language? Pyle isn't here to compete with Python, JavaScript, or any of the giants. The world probably doesn't need another programming language from me (not to mention written in Python). But I needed to build one. I wanted to tear away the layers of abstraction and see the guts.

I've been spending the last couple weeks in my spare time making a web based 3d skydiving simulation software utilizing ThreeJS designed to realistically visualize and simulate how a skydive unfolds from exit to canopy deployment. I had a couple of motivators starting this project - I recently returned to school to pursue a degree in Physics, but learning so much mathematical theory naturally inclined me to want to apply it to real world situations. After recently completing a skydiving training program, one thing became clear: there’s a serious lack of tools to help visualize where we are in the sky relative to other jumpers. Only after about 30 jumps do we gain the situational awareness to see where others are. I've designed this to help jumpers understand spatial awareness, separation, and freefall dynamics and how wind affects them in a more intuitive way before they even step foot on the plane. So far, the software includes A frame-by-frame time scrubber to review and analyze movement from any point Modular UI components that change the variables of the skydive A flexible camera system to observe from any position, or fixed to a jumper or plane Real weather data based on longitude and latitude (Pulled from Open-Mateo.com) Dynamic satellite imagery of chosen dropzone (Mapbox.com) Choose between 4 different planes with different flight characteristics (DC-9, Skyvan, Twin Otter, Cessna-172) This is just the beginning, but I hope that this passion project turns into something that can effectively assist others in preventing injury and accident in the sky.  ( 3 min )

Facing the challenges of AI-assisted development with a collaborative solution In my previous exploration of "agentic dementia," I outlined the hidden costs of our growing dependence on AI coding assistants—the erosion of learning, the subscription trap of cognitive outsourcing, the gradual loss of craft, and the knowledge lock-in that comes with AI-powered development tools. But identifying the problem is only half the battle. The question that keeps surfacing is: what's the alternative? If AI assistance comes with these cognitive costs, how do we maintain productivity while preserving our essential human capabilities? How do we harness the benefits of modern development tools without falling into the trap of intellectual dependency? The answer, I believe, lies not in rejecting technology…  ( 11 min )

CONNECT GITHUB WITH GITHUB SSH KEYS For this step, check for existing SSH Keys and I did that on ubuntu bash and wrote ls -al ~/.ssh. This lists the files in your .ssh directory. Looked for files like id_rsa.pub, id_ecdsa.pub, or id_ed25519.pub. They were not there so next is generating them. ssh-keygen -t ed25519 -C "youremail@gmail.com" your_email@example.com" with your GitHub email address. eval "$(ssh-agent -s) ssh-add ~/.ssh/id_ed25519 cat ~/.ssh/id_ed25519.pub ssh -T git@github.com At this point I feel like I am an expert because I know that docker is; a container, see expert. Headed to google typed in docker install windows because my laptop has windows 64 bits but what is the difference between ARM and AMG, food for thought. Run it, and either create a docker account or sign in via google or github, I used google easy. I installed Windows Subsytem for Linux by first installing ubuntu 24.0.0 via microsoft store, and it installed wsl by default, set up ubuntU and I had wsl. Prior to this bootcamp I had VS Code already installed and these were the steps I took. Then later into my learning journey I installed git. Basically same steps as I did with vs code only this time type git install windows, run it and now you have; git bash, git gui and some git documentation as well.  ( 4 min )

What exactly is a referral and why do companies use them? A current employee of a given company submits the resume of someone they know for an open role (or otherwise vouches for/endorses), which may improve the odds or speed at which their application is reviewed. In essence, the current employee is personally recommending this other person as a good fit for the company/role (though there are nuances). Yes, I think this is the part candidates are most likely to misunderstand! At some companies, especially larger ones, all referrals aren’t created equal. The referrer may have to share quite a bit of information about how they know the person they are recommending and/or sort the referral into one on of several categories. Common categories of questions on the referral form include: Refer…  ( 6 min )

Beyond the Application: Your Secret to Job Search Success The job search can feel like a relentless cycle of applying, with low response rates. Many spend all their time hitting Apply neglecting crucial interview preparation. But when that interview call finally comes, being unprepared can ruin your chances. The real key to landing a job? A smart balance between applying and preparing. Don't just repeat your resume. Instead, elevate it by elaborating on relevant experiences and skills. Decipher the job description like a roadmap, understanding not just current duties but where the role will evolve. Connect your skills to their needs, showing how you'll benefit the company, not just what you can do. And research like a pro – dive into the company's blogs, news, and even other job descriptions to grasp their priorities and culture. To truly optimize your job search, timebox your efforts. For general activity, aim for a 70/30 split: devote about 70% of your time to actively applying and networking, and a crucial 30% to proactive, ongoing interview preparation. This consistent prep includes practicing answers, refining your pitch, and brainstorming questions. Critical Exception: The moment an interview is scheduled, flip your focus immediately. Shift all available time to intensive preparation for that specific opportunity – research, tailor answers, practice, and conduct mock interviews. This is when all your proactive effort pays off. By strategically balancing your application efforts with consistent, deep preparation, and knowing when to go all-in, you'll transform your job search and significantly boost your chances of landing that dream role. Good luck. What other job search or interview prep strategies have worked wonders for you? Share your insights in the comments below!  ( 3 min )

In the continuous missing to stay secure, I have earlier written about pinning your GitHub Actions in TIL posts: TIL: Pin Your Action Dependencies and TIL: How do I resolve the SHA checksums?. This is a good practice and with Dependabot helping you out, it makes it easier once you have the initial pinning done. For one of the projects I maintain, I got a PR and they stuck to the same good practice, but the comments was prefixed with the word "ratchet", which I had not seen before, so I had to do some research. ratchet is a small tool to help you with your pinning.

Keeping a Linux server’s disk space healthy is a critical, yet often overlooked, sysadmin task. Over time, logs pile up, Docker storage balloons, and application caches accumulate — eating into your precious disk space and causing performance or stability issues.

Here’s what commonly fills up disk space on Linux servers: Large and old log files in /var/log (including system logs and application logs like PM2’s) Systemd journal logs that grow indefinitely unless managed Docker storage layers and volumes that accumulate unused data Application cache folders (e.g., Node.j…  ( 5 min )

Active Learning Example: A Production-Grade Deep Dive 1. Introduction In Q3 2023, a critical fraud detection model at a major fintech client experienced a 15% drop in precision, leading to a surge in false positives and significant customer friction. Root cause analysis revealed a shift in fraudulent transaction patterns – a new attack vector exploiting a previously unseen feature combination. Retraining the model on the latest data helped, but the process took two weeks, requiring manual data labeling and a full model deployment cycle. This incident highlighted the limitations of purely passive model updates and the urgent need for a system capable of proactively identifying and learning from the most informative data points. This is where a robust “active learning example” implementati…  ( 7 min )

Axiom Bio has released a comprehensive dataset of liver toxicity profiles for AI-based drug safety assessments. The dataset includes high‑content imaging data from human hepatocyte cultures exposed to around 130,000 compounds. Each compound is accompanied by multi-channel fluorescence microscopy images and annotated phenotypic readouts reflecting liver cell health  oai_citation:0‡techlifesci.com. Multi‑label classification data for hepatotoxic vs non‑toxic responses High‑resolution cellular images with quantifiable phenotypic features Standardized metadata for compound concentration, exposure time, and assay conditions Exportable formats including CSV and NumPy arrays for seamless integration Example Usage from axiombio import HepatoDataset data = HepatoDataset("axiom_livertox_130k") img, label = data[123] print(label, img.shape) The toolkit also includes helper methods for data normalization, visualization, stratified train/test splitting, and integration with deep learning frameworks like PyTorch and TensorFlow. Drug‑induced liver injury is a leading cause of clinical trial failure and post‑market drug withdrawal. By providing a large, annotated dataset, Axiom Bio enables AI models to learn from biologically realistic images, potentially improving early safety prediction and reducing late‑stage drug failure. Developers can fine‑tune convolutional neural networks or train explainable models to classify toxicity outcomes, perform transfer learning, or extract toxicity‑related features for downstream analyses. Axiom Bio is organizing a community challenge for AI teams to benchmark their toxicity prediction models. The dataset is currently available via the company’s portal, with academic access granted free of charge. Sources https://www.techlifesci.com/p/weekly-techbio-highlights-45-biotech  ( 3 min )

I Like Feynman I'm a big fan of Richard Feynman. If you study physics, you usually end up reading his famous "Red Books," and from there, you get into his biographies. Feynman used to say, "If you can't explain something in simple terms, you don't understand it yourself." That's probably why he won a Nobel Prize for explaining theories with simple diagrams. Anyway, my point is, I don't get why people insist on explaining Object-Oriented Programming in such a ridiculously complicated way. I've been emphasizing that the biggest benefit of an interface is that it lets you define and enforce a contract in code. Another great benefit is polymorphism. I already explained this naturally when I talked about abstraction in the last part. If you just write up the contract, you don't have to care h…  ( 5 min )

In my last post, I wrote about how code reviews can go from helpful to harmful - how they sometimes slow teams down more than they support quality. But there's a deeper shift happening that changes the game entirely: developers aren't just reviewing each other's code anymore - they're reviewing AI-generated code. Tools like Claude, Copilot, and Cursor are becoming more capable every month. They're not just suggesting completions - they're writing entire functions, refactoring files, and even running tests. As they do, the developer's role is fundamentally evolving. We're no longer just authors of code. We're becoming curators, reviewers, and gatekeepers of what gets shipped.

That one line from Jovi Overo, CEO of Vault, perfectly captures the brutal reality of building in Web3. As a developer deep in the trenches of smart contracts, chain integrations, and ever-evolving tokenomics, I’ve seen this truth play out over and over again. What you build today might be obsolete tomorrow — not because it’s bad tech, but because someone else shipped faster, integrated better, or caught a wave you missed. In his interview with CoinStats, Jovi shares insights that should be required reading for anyone building in crypto, especially devs. Vault is aiming to merge decentralized finance infrastructure with embedded finance tools — essentially letting Web2 and traditional platforms tap into crypto-native features without friction. This is a huge signal of where the industry is going: abstraction, interoperability, and developer-first tooling. Here are a few points from the interview that really stood out from a dev perspective: 1. Fintech x Web3 = Embedded Crypto 2. Speed Is Strategy — but UX Is Survival Optimized RPC strategies Account abstraction (ERC-4337 is your friend) ZK-powered identity and KYC Gasless transactions or pre-paid models Developers who master the backend and the user journey will define the next cycle. 3.

In recent years, Haskell has transitioned from a niche academic language into a practical choice for production-level software. With its strong typing, purity, and expressive syntax, Haskell is becoming a serious contender for teams that prioritize code safety, maintainability, and long-term scalability. The Demand for Reliability As systems grow more complex and users expect near-perfect uptime, the cost of runtime bugs and unexpected behaviors has risen sharply. Haskell’s type system allows developers to catch many issues at compile time—often before they even hit production. This leads to cleaner, more predictable codebases. In 2025, development teams aren’t just chasing speed—they're chasing stability. Haskell provides exactly that. Functional Programming Goes Mainstream Functional pro…  ( 4 min )

Supercharge Your GitHub Copilot: How DevOps Engineers are Mastering Customisation Hey everyone! If you're a developer or, like me, a DevOps engineer, you've probably already experienced the magic that is GitHub Copilot. It's a game-changer, right? From suggesting boilerplate code to squashing annoying bugs, it feels like having an extra pair of hands (or rather, an extra brain) in your IDE. But here's the thing: out of the box, Copilot is fantastic, but it's also generic. It learns from billions of lines of public code, which is awesome, but it doesn't know your team's specific coding standards, your obscure internal libraries, or that quirky cloud configuration you spent weeks perfecting. And for us in DevOps, consistency, best practices, and domain-specific knowledge aren't just nice-t…  ( 10 min )

Recently, AWS announced the release of Strands Agents, an open source SDK that takes a model-driven approach to building and running AI agents in just a few lines of code. A while ago I built a city explorer using Knowledge Bases for Amazon Bedrock so to experiment with Strands Agents, I built the same application, this time using Strands Agents. Here's the process I followed: I already have Python 3.13 installed in my local machine, if you don't already have Python 3.10 or higher installed be sure to download an install it. I have an AWS account so I enabled model access for Claude 3.7 in Amazon Bedrock in the same region as the default region specified in my code later. Claude 3.7 is the default model used by Strands Agents. I then proceeded to set up my environment as follows: # Create …  ( 4 min )

Introduction In today’s digital landscape, applications must handle unpredictable traffic spikes without collapsing. Whether it’s a sudden surge in users or a distributed denial-of-service (DDoS) attack, systems need mechanisms to protect themselves from being overwhelmed. One such mechanism is load shedding, a defensive strategy that prioritizes critical functionality by selectively rejecting non-essential requests when the system is under stress. In this article, we’ll explore: What is load shedding, and why is it necessary? A practical demo that shows load shedding in action. By the end, you should understand how to apply this technique to keep your services resilient under pressure. Load shedding is the deliberate termination or deferral of non-critical requests to prevent system ove…  ( 5 min )

Originally posted on Methodox Wiki: Data-Driven Design. Modern software often needs to adapt quickly - whether that means processing new data sets, adjusting to user preferences, or deploying new features safely without downtime. To achieve such flexibility, software engineers increasingly adopt a methodology known as Data-Driven Design (DDD). Originally popularized by game development, Data-Driven Design emerged prominently in the 1990s as large studios confronted a challenging problem: the need to iterate rapidly on complex and interactive content. Game developers realized it was costly and slow to rebuild and redeploy an entire game every time designers wanted to tweak gameplay mechanics, adjust character behaviors, or revise in-game dialogues.

We live in a world where children are growing up with more access to the internet than ever before—but with very little understanding of how it actually works. We teach them how to use phones, tablets, and apps... But what if the real safety net isn’t just parental controls—it’s digital literacy? I believe one of the best ways to protect children online is to teach them how the internet is built—and that starts with learning to code. When kids learn the basics of how websites, web apps, and networks function, they gain more than technical skills.

Today's game-changer: git worktree (because context switching is expensive) You're deep in a feature branch, everything's messy, half-committed, and then: "Hey, can you quickly check that bug in main?" Your options: Stash everything, switch branches, lose your mental model Clone the repo again (and wait for node_modules to install... again) Commit incomplete work with "WIP: will fix later" All terrible. Git worktrees let you check out multiple branches simultaneously in separate directories: # Create a new worktree for hotfix git worktree add ../myproject-hotfix main # Now you have: # ~/myproject/ (your feature branch) # ~/myproject-hotfix/ (clean main branch) # Working on feature-xyz cd ~/myproject # Bug report comes in git worktree add ../myproject-hotfix main cd ../myproject-hotfix # Fix bug, commit, push git checkout -b hotfix/urgent-fix # ... fix and commit git push origin hotfix/urgent-fix # Back to feature work cd ~/myproject # Your half-finished work is exactly as you left it No context switching - your mental model stays intact No stashing - work in progress stays in progress Separate node_modules - no dependency conflicts Parallel development - review PRs while coding List all worktrees: git worktree list Clean up when done: git worktree remove ../myproject-hotfix Share .env files between worktrees: # In your main project ln -s ../myproject/.env .env I keep a dedicated worktree for code reviews: git worktree add ../myproject-review main Now I can review PRs without losing my place.

How a decades-old idea became the connective tissue for today’s AI era Picture a customer-service AI agent that politely answers questions until a user asks something just outside its training data. Suddenly the bot stumbles, hallucinating facts or looping back to “I’m sorry, I don’t understand.” What’s missing is context, i.e. a structured memory of how the world is stitched together that the model can query, reason over and update as reality changes. That structured memory is exactly what a knowledge graph (KG) provides, and in 2025 every CTO evaluating an AI or data platform seems to have “knowledge graph” on the whiteboard. Blame (or thank) large-language models (LLMs): they’re great at generating fluent text from patterns, but they still need a source of truth to ground their answer…  ( 7 min )

Ever tried to parse French numbers in your Ruby application? If you've worked with French text data, you know the pain: "quatre-vingt-quatorze" should become 94, "trois millions deux cent mille" should transform to 3,200,000, but good luck finding a performant solution that handles all the linguistic quirks of French numbers! That's exactly the problem I set out to solve with StringToNumber, a high-performance Ruby gem that converts French written numbers into their numeric equivalents with blazing speed and bulletproof reliability. French numbers aren't just "difficult", they're linguistically fascinating and computationally challenging: Special cases: "quatre-vingts" (80) vs "quatre-vingt-un" (81) Compound forms: "soixante-dix" (literally "sixty-ten" = 70) Multiple formats: "vingt-et-un"…  ( 5 min )

Good Morning everyone! Today I learnt about different types of selectors in CSS. There are mainly three selectors and these are: 1.CLASS: We create this by writing the tag name followed by class="some name" in whichever element we want to target. We can use the same class name for multiple elements and an element can have multiple class names also. In CSS we access the class by writing .followed by class name. For eg in the below code: Hello World This is an example of class selector .title { background color:"pink"; In this the element which has the class name of title will have it's background color as pink. The same class name can be used for multiple elements and in that case all those elements will also have the same style …  ( 4 min )

Hello everyone! I am building an agent using langchain, using Anthropic's 3.5 Haiku. I want to get the analytics of the model, such as number of input tokens, output tokens, cost per token, etc. When I fetch the number of input and output tokens from the json that is returned from the llm, there is a big difference in these numbers and the numbers which are displayed on the anthropic dashboard. I do not understand why and how to get an accurate number. Could anyone please share their insights regarding this problem? Thankyou  ( 3 min )

DomainKeys Identified Mail (DKIM) is a core component of modern email authentication. It allows domain owners to digitally sign outgoing emails. In this guide, we’ll explain DKIM in simple terms, why it matters, and how it works behind the scenes. Whether you're using an email delivery service like Sidemail, Sendgrid, Mailgun or similar, or managing your own mail server, this article will guide you through everything you need to know to get DKIM up and running smoothly. DomainKeys Identified Mail (shortly DKIM) is an email authentication standard that uses cryptographic signatures to verify that an email was truly sent by the owner of the sending domain and that it wasn’t altered in transit. It allows you (your service, application, or website) to “sign” its outgoing emails with a digital…  ( 9 min )

AI vs. AGI: What's the Big Deal? Ever wondered how your favourite social media app knows exactly what videos you'll love, or how your phone suggests the next word you type? That's Artificial Intelligence (AI) at work! But there's another, much more advanced type of AI that scientists and engineers are dreaming about: Artificial General Intelligence (AGI). Let's dive in and see what makes them different. Imagine a really clever calculator. It can do sums, complex equations, and even help with your maths homework, but that's all it does. That's a bit like Artificial Intelligence (AI). AI refers to computer systems designed to perform specific tasks that usually require human intelligence. Think of it as specialised smarts.

Introduction Vibe Data Analysis is an emerging paradigm in analytics where users instruct AI systems to perform data analysis using natural language instead of code or manual tools. In a Vibe-driven approach, you simply ask questions or gives high-level directives (the "vibe") and an AI powered by large language models (LLMs) handles the heavy lifting – from querying databases to generating charts and explanations. This concept shifts data analysis from a technical process to an intent-driven, conversational experience. In practical terms, Vibe Data Analysis is a conversational, AI-driven method of data analysis where users interact with data in plain language, and LLMs generate results, summaries, and visualizations in real time. The goal is to deliver fast, intuitive insights without r…  ( 31 min )

There’s a quiet shift happening in DeFi — and I think it’s long overdue. For years, we’ve relied on token incentives to bootstrap adoption. Yield farming, liquidity mining, governance rewards — they’ve worked well as initial traction models. But let’s be honest: they don’t scale forever. Inflation eats into sustainability, and users eventually chase the next higher APR. As someone deeply involved in DAO mechanics and product design, I’ve been thinking more about how DeFi protocols can create native revenue streams that are aligned with usage, not just funded by emissions. And one approach I believe is underutilized — yet full of potential — is the broker model. The Case Against Over-Reliance on Emissions Most DAO treasuries depend on token inflation. We incentivize liquidity with more toke…  ( 4 min )

A feature flag is a mechanism that allows specific functionality within an application to be enabled or disabled dynamically, without deploying new code. Feature flags play a pivotal role in modern DevOps practices by enabling teams to manage feature rollouts, control exposure to end users, and reduce risk during deployments. They are commonly used to disable incomplete or experimental features in production environments, enable gradual rollouts (such as canary or blue-green deployments), or restrict access to premium functionality based on user entitlements. For those of us working with AWS on a daily basis, AWS Systems Manager Parameter Store is a familiar and trusted service. It’s often used to store configuration values like URLs, hostnames, environment variables, and other runtime s…  ( 5 min )

APIs are the invisible infrastructure of the modern web. They power mobile apps, connect platforms, and fuel integrations. But building an API is not the same as building a product. If you’re in API product management, your users aren’t everyday consumers , they’re developers. And developers are the hardest audience to fake your way through. They’ll spot bad documentation, inconsistent behavior, or unclear error messages faster than you can say “stack trace.” So how do you build an API that developers don’t just tolerate, but love?

Imagine an engineer presents you with a new kind of engine. It is, they explain, unimaginably powerful, capable of solving problems that would take today's best engines billions of years. But there's a catch. Every single component within this engine—every gear, every piston, every wire—is fundamentally flawed. They vibrate uncontrollably, spontaneously break down, and forget their state millions of times per second. Would you trust this engine to power a city, discover a new medicine, or protect the world's financial secrets? This is not a hypothetical riddle; it is the central paradox of quantum computing.

Today's Task: Building the Contact Form Today, I began working on the contact form for my site. The form is still incomplete, but I was able to set up the foundational structure. Started with Directory Cleanup Before even opening the actual contact page, I found myself reorganizing the project directories and file structure. That took longer than expected and, by the time I turned to the page itself, most of the day had already passed. Handling Header Differences Between Pages One issue I encountered was that the contact page header needed to behave slightly differently from the main page. On the homepage, the header uses an isScrolled prop to apply visual changes during scroll. This small difference required more time to implement than I anticipated. Layout Struggles: Logo and Background Alignment Even though I copied the same CSS settings for background size and logo positioning, subtle misalignments kept appearing. It took quite a bit of tweaking to make things line up properly across both pages. Small visual inconsistencies like this can be surprisingly time-consuming. Current Status By the end of the day, I had the basic layout for the contact page in place. The structure is there, but it’s not yet styled or functional. Next Steps Tomorrow, I’ll start filling in the necessary form elements and polish the design using Tailwind CSS. My goal is to keep the layout clean and accessible, with smooth transitions and consistent spacing. Date: June 24, 2025 tags: portfolio, webdev, tailwindcss, nextjs, uiux  ( 3 min )

In the past few years, crypto sponsorships in sports have often felt like surface-level marketing moves — logos on jerseys, halftime ads, quick NFT drops. And for developers in Web3, this matters more than it might first appear. At its core, this partnership signals that crypto companies no longer see marketing as an isolated vertical. Instead, they’re embedding product-driven engagement layers into their partnerships. That could mean enabling on-chain ticketing systems, NFT-based loyalty programs with real-world perks, or crypto payment options for merchandise and events. These aren’t speculative ideas anymore — they’re becoming practical integration points. From a developer’s perspective, the potential here is quietly massive.

How Next.js Got Big Next.js has rapidly become the go-to framework for building high-performance, SEO-friendly, React-based applications since its launch in 2016. Let me explain why and how it got so big in the web development scene now. Next.js stands out by offering multiple rendering modes in one framework: Server-Side-Rendering (SSR): Fresh HTML is generated on each request, ideal for dynamic content or personalized pages. Static Site Generation (SSG): Pages are pre-built at build time, perfect for blogs or documentation sites, and served fast via CDNs. Incremental Static Regeneration (ISR): Combines the best of SSR and SSG. Static pages refresh in the background without complete rebuilds. These capabilities give developers control over performance, scalability, and content freshness per page. SEO-ready: SSR/SSG ensures search engines crawl full-rendered HTML, improving indexability. Core Web Vitals: Features like image optimization, code-splitting, and Turbopack boost metrics like LCP, FCP, TTI. In real-world cases, many teams meet Google's Core Web Vitals thresholds on first deployment (89%) with Next.js VS 52% with other frameworks. With the image component, Next.js delivers: On-demand, responsive image Lazy Loading Modern formats like WebP CLS prevention Zero-config setup: File-based routing, type support, hot module reloading work out of the box. Full-stack in a single repo: API routes, SSR/SSG, and middleware all coexist. No need for separate backend codebases. Turbopack: Next-gen build tool (Rust-based) that dramatically accelerates builds, faster than Webpack and Vite. Next.js isn't just another React boilerplate. It is a full-featured, versatile application framework. Whether you are building a blog, e-commerce platform, marketing microsite, or full-stack application, Next.js delivers a powerful foundation, so you can focus on delivering value instead of wiring up infrastructure.  ( 3 min )

As a beginner in web development, I recently completed a fun and educational project — a Recipe Explorer App. This project helped me practice HTML, CSS, JavaScript, and learn how to use JSON Server to handle data like a real API. In this blog post, I’ll walk through how I built it and what I learned in the process. 🧱 Project Overview Viewing a list of recipes with their ingredients and instructions. Adding new recipes through a form. All recipe data is stored and managed using JSON Server, which simulates a RESTful API and makes front-end development feel like it’s connected to a real back end. 🧩 Tools and Technologies Used JavaScript – to handle logic and DOM manipulation. JSON Server – to simulate a database and API. VS Code – my development environment. Git & GitHub – for version control and backup. 🔄 Displaying Recipes Here’s a basic example of the code: javascript http://localhost:3000/recipes') function renderRecipe(recipe) { ${recipe.name} ; document.querySelector('#recipe-list').appendChild(recipeCard); ➕ Adding New Recipes Here’s how the add feature works: javascript fetch('http://localhost:3000/recipes', { 🤯 Lessons Learned JSON Server is a great tool for simulating real APIs during development. Building this app helped me understand the importance of separating logic into functions. Small projects like this are perfect for learning how front-end and back-end parts connect. 📌 Final Thoughts In the future, I’d love to expand this project by adding edit functionality or search filters — but for now, I’m proud of what I’ve built. If you’re a beginner like me, I highly recommend starting with a small project like this. You’ll learn a lot and have fun doing it! 🧠 Pro Tip bash 📚 References JSON Server GitHub  ( 4 min )

Before we dive deep, let's clarify the two main policy types for S3: IAM Policies are attached to IAM users, groups, or roles and define what actions Bucket Policies are attached directly to S3 buckets and define who can Both use the same JSON policy language, but they serve different purposes IAM policies follow a standardized JSON structure that's both powerful and { "Version": "2012-10-17", "Statement": [ { "Sid": "AllowS3ReadAccess", "Effect": "Allow", "Action": [ "s3:GetObje…  ( 7 min )

Three years after Toyota's GR GT3 concept previewed a future halo car, its road-going counterpart – likely badged as the Lexus LFR – has been spotted testing aggressively in California. Veteran journalist Jonny Lieberman captured camouflaged prototypes on Angeles Crest Highway, revealing critical new details: Design & Stance: Even under wrap, the LFR's low-slung, wide-profile exudes purpose. Notably, the massive rear wing seen on earlier prototypes is absent, hinting at potential variants: A base model focused on street refinement. A track-focused version (or optional package) with aggressive aero. Performance Benchmarking: Lexus directly compared the LFR against a previous-gen Mercedes-AMG GT, signaling its ambition to rival established European GT cars. Support vehicles included…  ( 4 min )

Core Resiliency Patterns 1. Retry Pattern Uses a "retryForever" policy with constant backoff Configured with 5-second intervals between retries Set to unlimited retries (maxRetries: -1) to handle transient failures Applied automatically when component operations fail 2. Circuit Breaker Pattern Implements a "simpleCB" circuit breaker with three states: closed, open, and half-open Trip condition: Opens after 5 consecutive failures Timeout: Remains open for 5 seconds before transitioning to half-open Test requests: Allows 1 request in half-open state to test if service has recovered Recovery: Closes circuit if test request succeeds, reopens if it fails The resiliency patterns are defined in a YAML specification that includes: Policies section: Defines retry and circuit breaker behaviors Targets section: Specifies which components (like the statestore) the policies apply to Scoping: Applied to specific Dapr applications through the scopes field Normal operation: Application continuously saves and retrieves state via Dapr APIs Fault introduction: When the backing service (Redis) becomes unavailable, requests begin failing Retry activation: Failed requests trigger the retry policy with constant 5-second intervals Circuit breaker engagement: After 5 consecutive retry failures, the circuit breaker opens and halts requests Recovery testing: Circuit breaker periodically switches to half-open to test service availability Automatic recovery: Once the backing service is restored, the application seamlessly resumes normal operation This demonstrates how Dapr's resiliency features provide automatic fault tolerance for service-to-component interactions without requiring application code changes.  ( 3 min )

"Will AI replace frontend developers?" I've been asked this at least 17 times in the last month. And honestly, I'm tired of the fear-mongering. Let me save you the suspense: no, AI won't completely replace frontend developers. But it will absolutely transform how we work. The relationship between AI and frontend development isn't a death match – it's more like an awkward dance where both partners are still learning the steps.

In 2025, MVP in Agile has become a buzzword among founders. Whether you're building your first startup or contributing to your 20th sprint, you've probably heard the term MVP thrown around in Agile standups and planning meetings. But what exactly is an MVP in Agile development? Let’s clear it up — and truly understand what an MVP is. What is MVP? An MVP (Minimum Viable Product) is the most basic version of your product that solves a core problem for the user and can be delivered quickly to validate an idea. In simpler words: It’s the smallest thing you can build that delivers value to your users and lets you learn something real. In Agile, this fits perfectly into the philosophy of "build fast, learn fast." Why MVP Matters in Agile Agile development is all about iterative progress — bu…  ( 4 min )

Introduction ChatGPT has become a powerful ally for generating HTML and other code snippets. However, if you’ve ever tried working with the HTML code it outputs, you might have run into a small but persistent annoyance. To preview the HTML, we typically need to: ・Manually create an .html file This process may not be complex, but doing it repeatedly can become surprisingly tedious. To reduce that friction, I created a small web tool that lets you paste HTML code and instantly render it in the browser—without saving any files. 🔗 Try it here Copy the HTML code generated by ChatGPT Paste it into the input field on the tool’s page Click the “Render” button That’s it. The entire page will be temporarily replaced with your HTML content. No need to create or save any files manually. This tool uses document.write() to replace the document with your input. If your code contains syntax errors, the browser will usually provide helpful messages, and the line numbers in the console log remain consistent with your input. This makes debugging a bit easier as well. Opening and saving HTML files manually each time you want to make a change might seem trivial at first. But over time, it adds up and slows you down—like a slow-draining battery. With this tool, I hope to make your workflow just a little more efficient and enjoyable. It's available on GitHub, so I'd be happy if you could download it and place it on your desktop. Thank you for reading, and happy coding!  ( 4 min )

Over the past decade, we've witnessed the explosive rise of both blockchain and artificial intelligence. Yet as we bring these two forces side by side, a glaring gap becomes evident: Why Rebuild the Operating System for an AI-Native World? Smart contracts don’t initiate actions.

They evolve based on context. These two worldviews are structurally incompatible. You can’t encode intent-driven intelligence in if-else logic. You can’t build autonomous systems on top of stateless, call-and-return contracts. And you can’t expect systems built for finance to serve the needs of intelligent agents. Web3 infrastru…  ( 5 min )

Right now, you probably have at least fifteen browser tabs open. Maybe twenty. One for your email, another for that document you're supposed to review, three more for research you started but never finished, and countless others for tasks you've forgotten you even began.

Power BI is a powerful business intelligence tool that allows users to analyze, visualize, and share data insights in an interactive and user-friendly way. After learning how to use Power BI, I have discovered how effective it is in transforming raw data into meaningful reports and dashboards. One of the key features of Power BI is the ability to clean and prepare data efficiently. I can easily change data types, replace incorrect values, and handle missing values within the Power Query editor, ensuring the dataset is accurate and ready for analysis. In addition to cleaning data, Power BI allows the creation of new columns, measures, and even entirely new tables using DAX (Data Analysis Expressions) functions. DAX is a formula language designed for creating powerful calculations. With DAX, I can perform complex calculations like cumulative totals, conditional logic (similar to Excel's IF statements), and advanced aggregations to generate deeper insights. This makes it possible to create custom KPIs, ratios, and performance metrics that go beyond the standard summaries. Finally, building relationships between different tables is central to working with Power BI. The tool supports various types of relationships such as one-to-one, one-to-many, and many-to-one, which helps link different datasets together to create a comprehensive data model. Once the model is set, I can bring my analysis to life using interactive visuals like cards to display key figures, bar charts to compare performance, and slicers to filter data in real-time. Power BI has truly made it easier to explore data, spot trends, and communicate insights clearly and effectively.  ( 3 min )

A post by Vicente G. Reyes  ( 3 min )

Some frameworks tend to overcomplicate stuff that's otherwise trivial. We want to render some text whilst another process is pending, then display the results. Some people call this "Suspense". We can implement it as a simple stream that emits a placeholder initially and the final result when it's available. A BehaviorSubject from rxjs is all you need to get started. import { BehaviorSubject, switchMap } from 'rxjs'; import { rml } from 'rimmel'; const getData = () => fetch('/api').then(r=>r.text()); const suspended = new BehaviorSubject('Loading...').pipe( switchMap(data) ); document.body.innerHTML = rml` ${suspended} `; Try it yourself on Stackblitz So, why should you use this, instead of the alternatives? You could use Angular, but you'd have to convert this to a Signal. You could use React, but you'd need some adapter library such as react-rxjs. You could use Vue.js, but there you have to subscribe to the stream, update a signal and use that. Also, with most of these you'll have to manually unsubscribe from your streams to avoid memory leaks and clean up after yourself. Rimmel.js is the only UI library that makes it possible to use reactive streams directly in your templates, simplifying UI development considerably. It also simplifies the use of Observables, traditionally considered a particularly challenging endeavour. If RxJS is the best library for reactive streams, Rimmel is the best UI library for RxJS. Try it out now for a totally new development experience.  ( 3 min )

For the past few years I’ve been trying to build an operating system that can do everything you expect an operating system to do while also encoding its entire state as a single URL. That way, we get a permanent link to every O/S state, achieving truly comprehensive deep linking. For a long time, I struggled with finding a solid approach to achieving this goal. A user-friendly operating system involves many independent, dependent and otherwise tightly-coupled components — especially when you want it to be a platform that supports third-party app development. I tried a variety of different methods to encode/decode data from a string without redundancy. Some of my attempts involved query parameters, some of them base64-encoded JSON data, and some of them custom domain-specific languages. The…  ( 9 min )

🔍 Find All K-Distant Indices in an Array – LeetCode 2200 (C++ | Python | JavaScript) Om Shree ・ Jun 24 #programming #cpp #javascript #python  ( 2 min )

👋 Introduction Hey, algorithm adventurers! 🔍✨ Today we’re diving into a slick little indexing challenge from LeetCode — 2200: Find All K-Distant Indices in an Array. At first glance, it seems simple, but crafting an efficient solution requires a clever greedy strategy using pointers. Let’s break it down and uncover the logic behind this clean and optimal approach. 💡 You're given: An integer array nums An integer key An integer k An index i is called k-distant if there's at least one index j such that: |i - j| <= k and nums[j] == key Your task is to return all such indices in increasing order. The goal is to find all indices i such that within a window of distance k from i, there's at least one index j where nums[j] == key. Instead of checking every index i against all j, we can d…  ( 5 min )

Quick overview With the rise of large language models (LLMs) like OpenAI, Gemini, and DeepSeek, many companies are looking to integrate chatbots into their apps not just as support tools, but as intelligent advisors or agents. These chatbots can offer personalized, value-added services by giving the LLM context from the app itself, making conversations more relevant and useful to the user. In this post, we will create a chatbot using React and IndexedDB. We will use a wrapper called Dexie.js to help us implement our local database for storing information persistently..

txtai is an all-in-one AI framework for semantic search, LLM orchestration and language model workflows. Large Language Models (LLMs) have captured the public's attention with their impressive capabilities. The Generative AI era has reached a fever pitch with some predicting the coming rise of superintelligence. LLMs are far from perfect though and we're still a ways away from true AI. One big challenge is with hallucinations. Hallucinations is the term for when an LLM generates output that is factually incorrect. The alarming part of this is that on a cursory glance, it actually sounds like factual content. The default behavior of LLMs is to produce plausible answers even when no plausible answer exists. LLMs are not great at saying I don't know. Retrieval Augmented Generation (RAG) helps…  ( 11 min )

Hey, Vsauce. Michael here Alguns meses, descobri um dos melhores canais de todos os tempos. Talvez eu esteja um pouco chateada por não saber da existência dele antes. O Vsauce fala sobre absolutamente qualquer assunto, mas, acima de tudo, ele me ajudou a recuperar a curiosidade de entender o “porquê” das coisas. Conforme a gente vai ficando mais velho, muitas vezes paramos de questionar o mundo ao nosso redor. Mas o Vsauce não. Ele questiona tudo — e traz vídeos incríveis sobre temas aparentemente simples, como por exemplo: Por que batemos palma? Meu único objetivo com esse post é te perguntar: Obrigada, Michael (Vsauce), por ter me ajudado a reencontrar isso. :)  ( 3 min )

Welcome, fellow developers and curious minds! Have you ever wondered why some code feels like a detailed instruction manual, while other code feels more like a concise wish list? That's the core difference between imperative and declarative programming paradigms. In this article, we're diving deep into the world of declarative programming, exploring its power, elegance, and how it shapes some of the most fundamental tools we use daily, like SQL, HTML, CSS, and even the fascinating logic of Prolog. At its heart, declarative programming is about "what to do," not "how to do it." Imagine telling a chef you want a "delicious chocolate cake" instead of giving them step-by-step instructions on mixing ingredients, preheating the oven, and baking times. You declare your desired outcome, and the sy…  ( 7 min )

大規模なスタイルセットを記述する場合、CSS では限界があります。そこで登場するのが、CSS プリプロセッサ と呼ばれるツールです。その中でも代表的なのが SCSS (サス、Sassy CSS) です。 SCSS は CSS をより効率的かつ構造的に書くための拡張言語です。SCSS コードは、CSS に変換可能であり、実行時には CSS としてブラウザに解釈されます。 メリット SCSS 記法 メリット 変数 $primary-color: #007bff; 一括変更、管理のしやすさ ネスト .parent { .child { ... } } コードの可読性、構造の把握が容易 ミックスイン @mixin my-btn { ... } スタイルの再利用、記述量の削減 インポート @import 'variables'; ファイル分割、管理のしやすさ 変数: 色やフォントサイズなど、繰り返し使う値を定義して管理できます。変更があった際に一箇所修正するだけで済むため、メンテナンスが容易です。 ネスト: CSS セレクタを入れ子 (ネスト) にして書くことができ、HTML の構造を反映した、より読みやすいコードにできます。 ミックスイン: 繰り返し使う CSS のまとまりを関数のように定義し、必要な場所で呼び出して使えます。ベンダープレフィックスの管理などにも役立ちます。 インポート: CSS ファイルを分割して管理し、必要な場所でまとめて読み込むことができます。 $primary-color: #007bff; $font-size-base: 16px; .header { background-color: #f8f9fa; padding: 20px; h1 { color: $primary-color; // 変数を使った計算も可能 font-size: $font-size-base * 1.5; } nav { ul { list-style: none; padding: 0; li { display: inline-block; margin-right: 15px; a { color: #333; text-decoration: none; // & で親セレクタを参照 &:hover { // 色を暗くする関数 color: darken($primary-color, 10%); } } } } } } @mixin button-style($bg-color, $text-color: white) { background-color: $bg-color; color: $text-color; padding: 10px 20px; border: none; border-radius: 5px; cursor: pointer; } .primary-button { // ミックスインを呼び出す @include button-style($primary-color); } .secondary-button { @include button-style(#6c757d); } Vue プロジェクトで SCSS を使うには、SCSS をコンパイルするためのローダー (sass 等) をインストールする必要があります。 npm install -D sass そして Vue コンポーネントの タグに lang="scss" を追加します。 // ここに SCSS を記述 .my-component { h2 { color: blue; } } SCSS を導入することで、CSS によるスタイル定義を構造的に整理できるようになります。それによって大規模アプリでもスタイリングの管理がしやすくなります。  ( 4 min )

Text Compression for Beginners: Building Huffman Coding from Scratch in Swift Ever wondered how file compression actually works? This weekend, curiosity got the better of me, so I decided to dive deep and implement Huffman coding from scratch. 🌳 How Huffman trees work (with visual examples) 📊 Why Huffman is perfect for text/code compression 🔍 Step-by-step walkthrough of the "Mississippi" example ⚡ How to achieve ~50% compression on typical text files Unlike Run Length Encoding (great for images), Huffman coding shines with the kind of files we work with daily - source code, JSON, XML, plain text. It assigns shorter bit sequences to frequent characters and longer ones to rare characters. The best part? It's lossless - your original file is perfectly restored after decompression. A complete compression/decompression system including: Frequency analysis Huffman tree construction Bit-level file operations Compact tree serialization Ready to see how "Mississippi" becomes just 3 bytes?

DevOps — это не отдельная роль, а скорее философия или набор практик, принятых внутри компании/команды. За свой опыт я успел побывать, наверное, во всех вариантах «DevOps»: и как отдельный инженер, жёстко привязанный к команде разработки, и как инженер, Прежде чем поговорить о том, как проводить культурные изменения и нести в команду практики, призванные размыть границы между DevOps и разработкой, Это структура, к которой применимо описание «сисадмины на стероидах». Отдельная организационная единица, «Опять этой разработке что-то надо». «А давайте отполируем вот это решение, хоть оно и не несёт business value». «Давайте переизобретём свой костыль!» (чистейший NIH-синдром — Not Invented Here).

Learn how the Model Context Protocol (MCP) can power smarter, scalable, and stateless AI agent systems. If you’ve ever built anything slightly more complex than a simple chat interface with an LLM, you’ve probably run into the same wall most of us hit: Agents forget things. Context doesn’t persist. Coordination feels clunky. Everything breaks when scale enters. Welcome to the context crisis. The era of building LLM-powered tools and agents is here — but our infrastructure isn’t ready. Most devs are duct-taping memory, state, and agent logic into isolated silos, and calling it a day. But you know that won’t scale. What if you could separate the logic of what a system should do from what it knows and how it remembers? That’s where the Model Context Protocol (MCP) comes in — and no, this is…  ( 6 min )

Author: Tobie Morgan Hitchcock This blog post was inspired by Kolawole Samuel Adebayo's Forbes article on The AI Race Is Now About Databases — Not Just Big Models. The article is insightful to highlight that AI’s bottleneck is no longer compute, it’s about databases: data, storage, and memory. The last few weeks made that shift visible in capital letters, with multiple database acquisitions in the AI space. These aren’t just tech M&A headlines. They’re a collective admission: to scale AI, you first have to rethink how memory (not only data) is managed. The frontier has moved down-stack. It’s no longer just about building bigger models or fine-tuning LLMs. It’s about how agents access, reason over, and persist context in real time. In our conversations with enterprises, we’ve noticed that m…  ( 4 min )

Ever needed a centralized configuration manager in your JavaScript app? 🤔 In modern JavaScript apps, managing shared state or configuration often means reaching for heavy tools like Redux, Zustand, or context APIs. But what if you're working on a small utility, a framework-agnostic widget, or just need a simple global config? This is where the Singleton pattern with an IIFE (Immediately Invoked Function Expression) comes in handy. It offers a lightweight, zero-dependency way to encapsulate state, avoid global pollution, and keep things clean—all without introducing a full-blown state manager. const configManager = (() => { let config = {}; return { set(key, value) { config[key] = value; }, get(key) { return key ? config[key] : config; } }; })();…  ( 3 min )

Input Embedding Space Gradients This is the first in a series of posts on the question: "Can we extract meaningful information or interesting behavior from gradients on 'input embedding space'?" I'm defining 'input embedding space' as the token embeddings prior to positional encoding. The basic procedure for obtaining input space gradients is as follows: Transform tokens into input embeddings (but do not apply positional embedding). Run an ordinary forward pass on the input embeddings to obtain a predicted token distribution. Measure cross-entropy of the predicted distribution with a target token distribution. Use autograd to calculate gradients on the input embeddings with respect to cross entropy. The result is a tensor of the same shape as the input embeddings that points in the dire…  ( 7 min )

When working with geographic data in Python, calculating the distance between two points on Earth is a common task. But not all methods are created equal! Here’s a quick guide to the most popular approaches and why geopy.geodesic is often the best choice — especially if you're working on Django, GIS, or logistics platforms. Some libraries (or naive code) use the Pythagorean theorem to compute distance between lat/lng pairs: # ❌ Not recommended for geographic coordinates! from math import sqrt def euclidean_distance(coord1, coord2): return sqrt((coord1[0] - coord2[0])**2 + (coord1[1] - coord2[1])**2) The Earth is not flat. This method ignores the planet’s curvature, so it becomes wildly inaccurate as distances grow. These formulas treat the Earth as a perfect sphere: # ✅ Haversine e…  ( 4 min )

For decades, the narrative has been the same, the Big Tech, with its colossal R&D budgets, server farms, and armies of PhDs, sets the standard for customer experience. Their AI-powered recommendation engines, impossibly fast support bots, and hyper-personalized journeys have felt like an unachievable competitive goals. For most startup founders, small business owners, and product leaders, the game seemed rigged honsetly. but guess what That era is over. There are Three fundamental shifts have demolished the old barriers to entry whuich i called the great equalizer The API-fication of Intelligence: Foundation models like OpenAI's GPT-4, Anthropic's Claude, and Google's Gemini are now utilities. You can "rent" a world-class AI brain via a simple API call for pennies. Big Tech did the heavy lifting of training; you get to do the creative work of applying it. The Rise of the No-Code/Low-Code "Nervous System": You don't need a team of machine learning engineers to connect these AI brains to your business processes. Platforms like Zapier, Make.com, and Retool act as a central nervous system, allowing you to build sophisticated workflows that link your CRM, support desk, and marketing tools with powerful AI capabilities—often with zero code. The Agility Advantage: A small team's greatest superpower is its proximity to the customer and its lack of bureaucracy. While a Big Tech company debates a new feature in committee for six months, you can identify a customer pain point on Monday, build a prototype AI solution on Wednesday, and deploy it by Friday. The game has changed. The resources are in your hands, the cost of entry has collapsed, and the agility of a small team has never been more valuable. The question is no longer if you can compete with Big Tech on AI-powered customer experience. The question is, how will you choose to win?  ( 4 min )

Rust is known for being safe and fast but to get there, you need to understand some core concepts. Let’s break down lifetimes, traits, enums, and pattern matching with clear examples. Rust makes sure you don’t use data that’s already gone. Lifetimes are how Rust tracks how long references are valid. fn longest(x: &'a str, y: &'a str) -> &'a str { if x.len() > y.len() { x } else { y } } This function returns the longer of two string slices. The tells Rust: "The result reference will live as long as both x and y." ✅ Without this, Rust won’t know how long the returned reference lives and could reject your code to keep things safe. Traits define what methods a type must implement. Think of them like "skills" a type can have. trait Speak { fn speak(&self); } struct Dog; …  ( 4 min )

I didn’t set out to make a reading list. Honestly, most of the books I’ve found useful were ones I stumbled on. A friend mentioned it, or I saw it in a strange corner of a bookstore, or I picked it up, put it down, then picked it back up two years later when something in my life finally made me ready for it. What’s strange is, a lot of them weren’t directly related to work. Not in the obvious way. They weren’t books about “career growth” or “leadership hacks.” But they shifted something in me—how I make sense of chaos, how I ask questions, how I interpret what’s not being said in a room. So no, this isn’t a ranked list. I’m not trying to be helpful or definitive. I’m just trying to trace a line backward—through the ideas, arguments, phrases, and small turning points that stuck.

Blazor Server makes it easy to build web apps with intuitive syntax, but handling dates and times (DateTime) requires special attention. Can you spot the bug in the following code? @DateTime.Now.ToString("yyyy-MM-dd HH:mm:ss") The answer: This displays the current time on the server, not the user's local time. The time is formatted according to the Blazor host server's time zone, which may not match the user's time zone. This bug occurs when the Blazor host server's time zone ≠ user's time zone. It's a subtle issue that's easy to miss during development. A similar problem arises with date/time input fields. You can't tell which time zone the entered value refers to. @code { private DateTime dt { get; set; } p…  ( 5 min )

DX-First Thinking: Why I Added @EnableTenantIsolation to My Spring Boot Starter Day 3 of building multi-tenant-springboot-starter was less about code, more about mindset. I wanted developers to switch between DATABASE, SCHEMA, and SHARED isolation strategies for tenants. The default Spring Boot way would be application.yml: tenant: strategy: DATABASE That works, but I asked myself: “What would it look like if Spring had built this?” So I created: @EnableTenantIsolation(strategy = TenantIsolationStrategy.SCHEMA) 💡 This annotation uses ImportBeanDefinitionRegistrar and EnvironmentAware to inject the tenant.strategy key into the Spring Environment — before anything binds. What I learned: @import(...)

Mastering Data Compaction in Apache Iceberg: A Production Deep Dive Introduction The relentless growth of data in modern applications presents a significant engineering challenge: maintaining query performance on ever-increasing datasets. We recently faced this at scale while building a real-time analytics platform for a large e-commerce company. Ingesting clickstream data at 100K events/second, coupled with historical order data totaling over 500TB, resulted in query latencies exceeding acceptable thresholds for dashboarding and reporting. The root cause wasn’t compute or storage capacity, but the proliferation of small files and inefficient data layout within our data lake. This led us to deeply investigate and optimize data compaction strategies within Apache Iceberg, a …  ( 7 min )

VoiceReach is a voice message broadcasting tool that lets users send a single typed message to multiple recipients via automated phone calls. The app uses a Text-to-Speech (TTS) API to convert the message into a realistic voice and then places calls using Twilio to deliver the audio. Designed for quick announcements, invitations, or alerts, VoiceReach eliminates the need for repetitive manual calls, making communication faster and more efficient. Built with Node.js, Express, and a simple HTML/CSS frontend, it's a powerful yet user-friendly solution for voice-based outreach. GitHub repo - https://github.com/madhavdandona123/murf-ai VoiceReach has powerful real-world applications for anyone needing to deliver voice messages to multiple people quickly and reliably. Community leaders, school administrators, event organizers, political campaigners, and small businesses can use it to send announcements, alerts, or invitations without making manual calls. It’s especially useful for reaching people who may not regularly check texts or emails—such as elderly recipients or rural communities. Compared to traditional methods like group calls or bulk SMS, VoiceReach improves efficiency by automating the process with natural-sounding voice and delivering it through a personal phone call, which feels more direct and urgent. It reduces human effort, saves time, and increases the likelihood that important messages are heard.  ( 3 min )

Adding alias in your Gitbash terminal can help you speed up your workflow when using the terminal. ⚡️ In this tutorial, I am going to guide you how you can configure the aliases for your day-to-day commands. 🚀 First of all open the Gitbash and type following command in it. alias And you will see an output something like below image. It will give the list of aliases which are configured. 📋 If you see nothing, then no aliases are set. So don't worry. 😅 To set the alias for any command type following in the terminal. ✨ alias new_command_name='old_command_name' The alias set within the image will create an alias for git commit. Now I can just type gc -m and it will commit my code. 🎯 And that's it, you have configured your first alias. Hurray!!! 🎊 Hold on, it's not over yet. ⚠️ If you just close the terminal and try to re-run that alias again, it will throw error like this. 😱 What?! You will think I just set it and now it's gone. Yup it's gone. 💔 Because aliases set with alias are session based means they are deleted once the terminal is closed off. So how can we make it permanent??? 🤔 Well, there is a way make it permanent. 💡 It's .bash_profile file, it's location differ from OS to OS. For windows it would be OS_Drive/Users/ and for ubuntu it's present in root and you can run ls -la to see it. 📁 Open the .bash_profile file and edit it. ✏️ Congratulations. You have created your first permanent alias, I repeat first permanent alias of your. 🏆 Now you can configure as much as aliases you want, and you just need to add them within .bash_profile file. 🔧✨  ( 4 min )

Remember the first time someone asked you to "put that data in a report"? You probably stared at your perfectly good SQL query results and thought, "Isn't this already a report?" Then you realized they wanted something their boss could actually look at without squinting at raw data tables. Here's the thing nobody tells new DBAs: Writing great queries is only half the job. The other half is making that data speak to people who don't think in SELECT statements. That's where SSRS comes in. And no, it's not as scary as it sounds. SSRS (SQL Server Reporting Services) is Microsoft's tool for turning your SQL query results into professional, interactive reports. Think of it as a translator between your database and everyone else. You know that query you wrote to check which products are selling …  ( 5 min )

Tired of checking Amazon every day to see if a product’s price went down? So was I. That’s why I built a simple tool that automatically tracks prices on multiple Amazon items and alerts me when they drop — no browser extensions, no manual checking. In this post, I’ll walk you through: The problem that led me to build this How it works behind the scenes Key features Lessons I learned And how you can get or build something similar I often add items to my Amazon wishlist and wait for discounts. But unless I checked manually — daily or weekly — I’d miss the best deals. Most price-tracking extensions are: Browser-dependent Limited to one product Bloated or subscription-based As a developer who loves automating boring stuff, I knew I could do better.

Hey folks. So what now, fellow developers? Panic, or polish your résumé and lean in? Inside this whirlwind sits both risk and an outsize slice of opportunity that might not show up again in our lifetimes. Let me live-code the explanation for a second. Forget the power-point speak; think of AI as the capability to feed an algorithm mountains of observations and then let it tweak its own playbook as fresh examples roll in. The decision logic emerges from the pattern, not from a human’s final check-mark. Artificial intelligence acquires proficiency in much the same way a specialist absorbs lessons from practice. An influx of fresh information typically translates into perceptible improvement. Professors and practitioners usually separate three principal disciplines within the field. Machin…  ( 6 min )

Hi, It’s been a while since I posted anything tech-related. So, my friends, here we have it. This article is all about how and why I used MindsDB for my next project: KbNet. Before I go deep into the technical rabbit hole, let me quickly tell you what MindsDB is. MindsDB is this cool open-source project that makes building AI-driven applications super smooth. It basically reduces the headache of connecting a bunch of data sources and managing AI integrations in your app. So instead of writing custom adapters and creating extra packages for every new data source, MindsDB just says: "Relax, bro, I got you." Connect multiple data sources and pipe them into a unified output. Create pre-built AI models with prompt templates (supports OpenAI, Google Gemini, and more). Run background jobs and…  ( 6 min )

Introduction Machine learning is no longer an experimental discipline—it's a cornerstone of critical infrastructure in industries ranging from finance to healthcare. As a result, model archiving has become a non-negotiable aspect of operational machine learning. In this blog, we explore what ML model archiving is, why it matters, and how Jozu and KitOps ModelKits provide the most robust, scalable, and future-proof ML Model Archiving Tool available today. ML model archiving is the process of storing machine learning models—along with their metadata, dependencies, training data references, and environment settings—in a secure and retrievable format. Model archiving is critical for several reasons: Auditability & Compliance: Regulations like GDPR, HIPAA, and the EU AI Act increasingly requi…  ( 5 min )

Countless applications. Hundreds of rejection emails. Failed interviews. It was easily one of the worst experiences of my career. Let me tell you how I eventually found my current job. It was May 2023. I saw a new meeting pop up on my calendar with no description, just an invite. Instantly, I knew what it was about. Companies were laying off developers left and right. I had already heard rumors about cuts at my company too. When I joined the call, I saw my HR representative. She told me that I was being laid off along with the rest of my team. My heart sank. I didn't know what to think or do. I accepted it quietly, packed up my things, and left the company that same day. It was a weird feeling, I'd never been laid off before. I'd always left companies on my own terms. This was completely d…  ( 5 min )

Today! We’re going to learn TypeScript like you’re a smart 5-year-old who loves to build things and asks “why?” (which is the best thing ever). & yes “why?” is my way of learning. I've divided this into 20 Chapters. and will go one by one and each will be of 2 - 3 min. of read. This is Chapter ⓵ TS Mastering 🤔 Imagine this: You’re building a toy robot (Yes, we are learning it like 5) . In JavaScript, you just glue parts together however you like even if you accidentally attach a banana instead of a motor… the robot won’t complain until it breaks later! 🍌🤖💥 But with TypeScript, it’s like having a smart helper who says: “Hey! That’s not a motor... that’s a banana. Are you sure you want to do that?” That helper saves you from mistakes before you even turn on the robot. Cool, right? TypeScript = JavaScript + Superpowers (called Types) write safer, smarter code. TypeScript helps you catch errors early It makes your code easier to understand It works great with modern tools and editors 💬 Let’s look at a simple example: // JavaScript function add(x, y) { return x + y; } add(5, "10"); // 🙃 oops! This gives "510" instead of 15! Now in TypeScript: function add(x: number, y: number): number { return x + y; } add(5, "10"); // ❌ ERROR! You gave me a string, I wanted a number! TypeScript tells you before you even run it that something’s wrong. Yes‼️ TypeScript is just JavaScript with extra safety. type annotations. 🐞 Catch bugs before they happen 👯‍♂️ Work better in teams 💻 Get amazing auto-suggestions in your code editor If you enjoyed this and want to master TypeScript and other technologies, follow the series and drop a like!🤝 I’m a passionate software developer sharing the cool things I discover, hoping they help you level up on your coding journey.

Day One was me reacquainting myself with Figma. I started by reviewing the basics of the interface and exploring the various tools and features available. I also took some time to familiarize myself with the keyboard shortcuts and the different ways to navigate the canvas. Juxtopposed video on this was super helpful and is what kicked off this idea! Who doesn't like cards on websites. They come in all sorts of... well not shapes but sizes and designs. I've seen truly beautiful ones and wanted to get better with playing with multiple layers. I knew I wanted a simple card consisting of a header, small paragraph, an icon, and a gradient. I often see cards come in threes and when I'm playing with colors in counts of three it's very difficult for me to not think of Pokémon, so I just went with it! There are actually several layers to each card: A circle with it's midpoint roughly anchored to the card's bottom right corner. A rectangle above it acting as a mask for the circle and bringing in the darker emerald/blue/rose colors. A rectangle of the same size above that with a semi-opaque and lighter emerald/blue/rose color with an inner-shadow of the darker color. The text and icon are the final layers. Even the button has a semi-transparent background which allows the main color to bleed through, as well as a semi-transparent border. These are simple but I like them! There is no goal to do one per day, but I’d like to do at least four three week so I can see progress. I also plan to write a short blog (or micro-blog, if you will) about each design I create or copy. If you’re in a similar boat, I encourage you to jump on board and do the same! I’ll be sharing my progress on X/Twitter and LinkedIn. If you’re interested in following along, feel free to follow me on those platforms!  ( 3 min )

If you are a developer or a system administrator, you might have heard of Docker and Virtual machines. Both are technologies that allow you to run applications in isolated environments, but they have different advantages and disadvantages. In this article post, I will compare Docker containers and virtual machines, explain their use cases and examples, and help you decide which one is better for your needs. A virtual machine (VM) is like a mini-computer that runs inside your main computer. It has its own operating system, memory, disk space, CPU, network interface, etc. You can run any application on a VM as if it was running on a real computer. For example, you can run Windows on a VM inside your Linux computer, or vice versa. Some of the benefits of using VMs are: They provide full isola…  ( 5 min )

DeFi isn’t exactly known for stability. Between hype cycles, market-wide volatility and social-media-triggered moves, most tokens tend to mirror the chaos around them. But every now and then, a token breaks that pattern. In 2025, $WBT coin has shown a different trajectory - not only resisting downturns, but reaching five new all-time highs in less than six months! While most centralised exchange tokens ($BNB, $OKB, $KCS, $GT) have stayed flat or fallen below their historical highs, $WBT has continued climbing. For reference: $BNB hit its ATH of $788.84 in Dec 2023 and hasn't surpassed it since $OKB last peaked in Mar 2024 $KCS hasn’t seen a new ATH since 2021 $GT joined WBT in reaching a new ATH in 2025 🧨 There are several macro signals that align with WBT's recent rise, and prove its growth as infrastructure-backed: trading volume surged alongside each ATH; liquidity pools deepened, especially post-margin launch; holder count steadily increased (on-chain data shows consistent wallet growth). WBT's case challenges a common assumption in crypto: that price action must come from hype & artificial pump. In contrast, it shows that consistent development, deep integration and clear tokenomics can still drive growth - even in noisy market conditions. For a deeper dive into WBT's recent performance, check the full article from CoinMarketCap. If you're building in 2025, WBT is a reminder that steady growth still comes from solving real problems, not just riding trends.  ( 3 min )

CSS とは Web ページの見た目を装飾するのが CSS (Cascading Style Sheets) です。HTML でページの骨格を作り、それに対して CSS で色、フォント、レイアウトなどを指定します。 CSS では、HTML 要素にスタイルを適用するためのルールを記述します。 セレクタ { プロパティ: 値; プロパティ: 値; } 用語 説明 例 セレクタ どの HTML 要素にスタイルを適用するかを指定します。 (下記「セレクタの種類」参照) プロパティ 変更したいスタイルの種類 color, font-size, margin 値 プロパティに設定する具体的な値 blue, 16px, 10px 20px セレクタは以下の 3 種類に大別されます。(疑似要素を含めるともう少し増えます。) これらを使い分けることで、スタイル適用範囲に幅と柔軟性を持たせることができます。 種類 例 要素セレクタ p { color: blue; } (すべての 要素) class セレクタ .my-button { background-color: green; } (タグに　class="my-button" 属性を持つ要素) ID セレクタ #header { font-size: 24px; } (タグに id="header" 属性を持つ要素) h1 { /* 文字色を濃いグレーに */ color: #333; /* フォントサイズを 32 ピクセルに */ font-size: 32px; /* テキストを中央揃えに */ text-align: center; } .button { /* 背景色を青に */ background-color: #007bff; /* 文字色を白に */ color: white; /* 内側の余白 */ padding: 0.2em 0.4em; /* 枠線をなくす */ border: none; /* 角を丸くする */ border-radius: 0.2rem; /* マウスカーソルをポインターに */ cursor: pointer; } .container { /* この要素を Flexbox コンテナにする */ display: flex; /* 子要素の水平方向: 両端に配置 */ justify-content: space-between; /* 子要素の垂直方向: 中央に配置 */ align-items: center; } Vue ではスタイルをどこに書くのでしょうか。 一つの方法は、すでに見た単一ファイルコンポーネント (SFC) すなわち .vue ファイルの中で タグに記述する方法です。そのコンポーネントに特化した CSS を記述できます。 共通のスタイルやユーティリティ class 定義を外部ファイル (.css) に記述することも可能です。希望の場所で読み込んで使用します。  ( 3 min )

I've been a longtime fan of a puzzle website with 40 incredibly well-made intellectual games. Recently, I decided to give it a modern overhaul. I don't have much front-end development experience, so I used Cursor and Claude to assist me throughout the process. I want to share why I decided to refactor this classic collection and how I efficiently accomplished this task with the help of AI, especially tools like Claude. Many years ago, I first encountered Simon Tatham's Portable Puzzle Collection. It's a set of brilliantly conceived and logically rigorous games, all written in C, capable of running on various old devices. I was hooked, completely captivated by their clever design. I even took a look at his C source code, and it's beautifully written. The author also developed PuTTY, which i…  ( 6 min )

Recently, I participated in the Forge Quest Hackathon by Atlassian—and it turned out to be exactly the kick I needed. For a long time, I had let my Postman Doc app on the Atlassian Marketplace go stale. Life happens. Forge evolves.

Our jobs require a certain level of precision, so it’s natural that we’ll want to take an exact approach to our software delivery metrics. Some folks might even like a detailed standard to pin their measurement to so they can be sure it’s exactly right. Investing too much in precision is wasteful and takes time away from something far more important: doing something in response to the data. The DORA metrics are the most popular DevOps metrics. The precision needed for DORA metrics is low, and gets even lower the higher you perform. In general, you want to get a temperature check for the kind of performance you have. For the throughput metrics, the unit of measurement is more informative than the number. It’s more interesting whether you measure throughput in months, weeks, days or hours th…  ( 6 min )

Page speed matters more than ever. Google’s Core Web Vitals framework has made TTFB and FCP crucial for ranking well. After hitting limitations with SSR, we decided to move to SSG + ISR on two of our most active content sites: nolcardbalanceae.com — public transport and NOL card balance check guides wgustudentsportal.com — student tools and academic resources Both platforms initially used getServerSideProps, but with traffic rising and SEO slipping, performance audits with PageSpeed Insights and Lighthouse confirmed what we feared: server response time was hurting the experience. We migrated to getStaticProps with Incremental Static Regeneration (ISR), letting us statically generate thousands of guides and tools for both nolcardbalanceae.com and wgustudentsportal.com. return { The result? Pages served instantly, with fresh data reloading in the background. Vercel’s 45-minute build limit created a blocker during deployment. With so many static pages, we exceeded the threshold regularly. To fix it: We batched content at build time Stored it as local JSON Called that in getStaticProps() This brought total build time below 30 minutes and gave us predictable, fast deployments. After implementation: nolcardbalanceae.com saw bounce rate drop by 20% wgustudentsportal.com pages loaded under 1 second Lighthouse scores consistently hit 95+ Googlebot crawled 3× more URLs per day We followed Next.js best practices and Google’s performance guidelines to the letter — and it paid off.  ( 3 min )

About a year ago, a dev friend of mine landed a job at a well-known product company. He was crushing it: delivering on time, writing solid tests, picking up weekend hotfixes — even showing up to standups with a fever. Then came the performance review. His manager told him: you’re not Senior yet. You lack confidence and initiative.” It hit hard. Especially after months of 60+ hour weeks and constant firefighting. A month later, he quit. He joined another company. Senior Software Engineer title. Now here’s the question: 💬 Who was right — the first company that didn’t see a senior, or the second that saw one immediately?

Let’s get something straight: your code is not a majestic redwood. It’s a houseplant. A needy, fickle little thing that demands regular sunlight, occasional pruning, and a watchful eye—lest it curl up, die, and stink up the whole damn repo.

Generative AI has exploded into the mainstream, with Large Language Models (LLMs) like GPT-4 leading the charge. But as impressive as these models are, integrating them into real-world applications requires more than just an API call. That’s where LangChain comes in. In this post, I’ll walk you through how LLMs and Generative AI work together — and why LangChain is becoming the go-to framework for building intelligent, context-aware AI applications. At its core, an LLM is a machine learning model trained on vast amounts of text to understand and generate human-like language.

For centuries, the image of education has remained stubbornly consistent: a teacher imparting knowledge to a room of students. But beneath the surface, a quiet revolution is underway. Artificial intelligence is no longer a futuristic fantasy; it’s actively reshaping how we learn, how we teach, and even what we learn. This isn't simply about digitizing textbooks or automating grading—it’s a fundamental shift in the architecture of education, a move toward systems that adapt, personalize, and anticipate the needs of every student. But the promise of AI in education isn’t without peril. As algorithms permeate the classroom, critical questions around equity, privacy, and the very nature of human learning demand urgent attention.

Serving static files—like CSS, JavaScript, images, or fonts—is a basic requirement for any web application. Even in a minimal Python framework, you can add support for static file delivery with only a few lines of code. Static assets are essential for rendering pages and enhancing UX. Without them, even the most functional web app will look and feel incomplete. You may use a reverse proxy (like Nginx) in production, but during development or for embedded apps, your framework should handle static file serving directly.

Launching a WordPress site in 2025 isn’t just about spinning up a theme and hitting “publish.” With users expecting faster performance, mobile responsiveness, and secure UX out of the gate — your launch process has to be strategic. I’ve launched sites for clients and personal projects, and I noticed a recurring pattern: the same pre-launch mistakes cause headaches later. So I started using a structured checklist — and it’s made all the difference. Here’s a breakdown of what I now do before going live with any WordPress site. Choose a reliable host (SSL, backups, fast support) Register a clean, brandable domain Ensure server location suits your target audience (e.g., US-based server for US traffic) Yoast SEO or Rank Math (SEO) UpdraftPlus (backups) Wordfence or Sucuri (security) Elementor or block-based editor for layout Use a responsive, lightweight theme Customize branding elements (colors, fonts, CTAs) Test across breakpoints (mobile/tablet/desktop) Enforce strong passwords & 2FA for admin users Update all plugins/themes before launch Install firewall + login protection plugin Meta titles + descriptions XML sitemap submission Keyword-optimized content + internal linking Compressed images + alt tags Google’s Mobile-Friendly Test ✅ Optimize for Core Web Vitals (LCP, FID, CLS) Check tap targets, menu responsiveness No broken links or 404s Contact forms working Speed test (PageSpeed, GTmetrix) Full backup before going live I’ve put together a detailed checklist that includes exact tools, plugins, and tips I use with clients.

I remember the first time I struggled to add the same extra behavior to many functions. I had a logging requirement on every class method, so I tried subclassing or adding if checks everywhere. My code became a tangled web of inheritance and flags. Then a colleague showed me decorators – and my mind was blown. A decorator is like giving your function a special coat: you wrap extra behavior around it without changing its core logic. As one tutorial puts it, decorators “allow you to wrap another function—to add or modify its behavior—without changing the original function’s code”. It felt as elegant as putting a gift in a beautifully decorated box. enhances it. In the same way, a decorator takes your function and adds “frosting” – extra logging, timing, authorization checks, etc. You still …  ( 8 min )

The introduction of React 19, Server Components, Server Actions, and other developments such as the React Compiler (Forget) are leading the ecosystem towards a more declarative, reactive and server-focused paradigm. We will deconstruct in this blog: Why useEffect can be more troublesome than helpful? What the modern React provides as alternatives that are cleaner? Practical cases in which useEffect can now be eliminated When is useEffect necessary? (Img Source) What Replaces use…  ( 5 min )

We've all been there. You're building an awesome app, everything's going smoothly, and then you hit that requirement: "Oh, and we need to send welcome emails, password resets, order confirmations, and notifications." Suddenly, your simple project turns into an email engineering nightmare. 📧💀 The Email Development Black Hole // What it actually becomes: // 200+ lines of email configuration later... According to recent surveys, developers spend an average of 40+ hours just building and maintaining email systems. That's a full work week that could be spent on your core product features! The Hidden Complexity of "Simple" Emails Template Management: HTML emails that work across all clients Each of these could be a project in itself. javascript// Traditional approach - hours of work // AI-powered approach - one line ✅ Professional email design Real-World Example: Password Reset ; // After: Natural language Send a secure password reset email with a button linking to ${resetUrl}. }); The AI generates a professional, secure-looking email with proper styling, clear call-to-action buttons, and even includes security messaging automatically. From Template Hell to Natural Language No more managing multiple template files From Hours to Minutes Prototype emails instantly From Maintenance Burden to Set-and-Forget AI handles design consistency Getting Started Identify your email types: List all the emails your app needs to send The key is starting with simple transactional emails (welcome, reset, confirmation) and expanding from there. What's Your Experience? P.S. If you want to experiment with AI email generation, I've been testing it with contacted.io - they have a free tier that's perfect for trying out this approach. The interactive playground lets you test prompts before implementing.  ( 5 min )

** What Are Chrome Net Internals?** Chrome's Net Internals is a collection of diagnostic tools provided by the browser. It enables users to examine and control network-related information, such as DNS cache, sockets, proxy settings, etc. To launch: Enter chrome://net-internals/#dns in the Chrome address bar and hit Enter. Chrome, over time, caches DNS records to make websites load faster. Stale or damaged DNS records, however, may cause the following errors: DNS_PROBE_FINISHED_NXDOMAIN ERR_NAME_NOT_RESOLVED Weblinks failing to load Flush the DNS cache deletes these cached records so that Chrome can retrieve new DNS information from the network. How to Clear Chrome DNS Error on Windows Clear DNS using Chrome Net Internals Launch Chrome and go to: chrome://net-internals/#dns Click on “Clear…  ( 4 min )

Introduction YAML (YAML Ain't Markup Language) is a human-readable data serialization standard that has become increasingly popular for configuration files in modern programming applications. YAML combines the best features from Perl, C, XML, HTML, and JSON, creating a reliable and easily readable format. Due to its strong compatibility with JSON format, YAML files can be easily interchanged with JSON files. This guide focuses on fundamental concepts and commonly used patterns for those beginning to learn YAML. YAML files use the .yaml extension. Some systems that don't support extensions longer than three characters also use .yml. Important Rules: YAML is case sensitive Use spaces instead of tabs for indentation Tabs are prohibited due to varying tab settings across different editors A …  ( 8 min )

When I first decided to pursue the AZ-104 certification, I knew I was stepping into a more hands-on role within Azure’s ecosystem. Unlike foundational exams like AZ-900, AZ-104 dives into the operational responsibilities of an Azure Administrator—making it both rewarding and demanding. In this post, I’ll walk you through how I passed AZ-104 on my first try, covering everything from preparation strategies to exam-day tips. I had been working in a hybrid cloud environment for a while and realized that Azure was becoming more central to our infrastructure. To stay relevant and grow my skills, AZ-104 felt like the natural next step. It’s ideal if you’re looking to validate your ability to manage cloud services like virtual machines, storage, networking, and identity. Exam Code: AZ-104 Duration…  ( 4 min )

🔹 Problem: 2081 K Mirror Numbers Difficulty: Hard Tags: #Palindrome, #BaseConversion, #Math, #BruteForce Given two integers k and n, you are to find the sum of the first n positive integers that are palindromes in both base 10 and base k. k-mirror if: It's a palindrome in base 10 (normal decimal), and It's a palindrome in base k. Brute Force Idea: Check every number starting from 1, See if it's a palindrome in both base 10 and base k. Keep going until I find n such numbers. This idea is simple, but extremely slow and will TLE for large n. What I Figured Out: I realized that we should generate palindromes only in base 10 and check if they’re also palindromes in base k. This eliminates checking non-palindromic candidates, which saves a lot of time. I also figured that we can build palindr…  ( 4 min )

Read full Paper In this article, we explore the potential economic consequences of a hypothetical WWIII, considering not only physical warfare but also digital, economic, and AI-driven conflicts. While speculative, this analysis uses historical precedents, present vulnerabilities, and global interdependence to paint a realistic picture of a world economy torn by war. Collapse of Global Trade Networks WWIII would almost certainly paralyze international trade. Maritime routes would be militarized or blocked, airspace restricted, and shipping infrastructure targeted. The World Trade Organization (WTO) and other global frameworks would falter. Container shipping, which accounts for over 80% of global trade by volume, could grind to a halt. Supply chains, particularly those linked to semiconduc…  ( 5 min )
